AB  - The phase equilibria in the CeO2-xSiO2-ZrO2 system were studied in the subsolidus region in argon atmosphere, under isothermal heating and hot pressing, at 1400 degrees C, different ceria, silica, and zirconia mixtures. X-ray diffraction (XRD), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA) were performed to identify phases and to establish phase equilibria. Based on the results of many preliminarily investigated ternary compositions, possible tie lines are predicted. Compositions from the proposed tie lines were successively fired and ground until the changes of the phase compositions were not detected or were low enough to be neglected. Phases identified in these compositions confirmed the existence of five tie lines: Ce2Si2O7-ZrSiO4, Ce2Si2O7-ZrO2, Ce-4.67(SiO4)(3)O-ZrO2, Ce-4.67(SiO4)(3)O-Ce2Zr2O7 and Ce2SiO5-Ce2Zr2O7, which divide the CeO2-x-SiO2ZrO2 composition triangle into six compatibility triangles. The formation of ternary compounds or ternary solid solutions in the CeO2-x-SiO2-ZrO2 system was not observed. The monoclinic high temperature polymorph of Ce2Si2O7 was detected. The cubic pyrochlore phases had different lattice parameters, caused by incomplete reduction of the tetravalent cerium ions also observed in the non-stoichiometric cerium oxide.

AB  - Studying solid state reaction between mechanically activated oxide powders of CeO2 and quartz-SiO2, we obtained directly during heat treatment, the low temperature polymorph of Ce2Si2O7 instead of the high temperature polymorph formed in non-activated oxides mixture. The mixture with composition corresponded to Ce2Si2O7 stoichiometry was mechanically activated by milling in high energetic vibratory mill for 2-120 min. Heating was done in an Astro furnace in a flowing argon atmosphere at 1200-1550 degrees C for 1 h while the specimens were furnace cooled. Crystallite size, lattice distortion and phases identification was performed by X-ray powder diffraction (XRD) analysis. Microstructure characterization of the mixtures was done using scanning electron microscopy (SEM). Low temperature polymorph of Ce2Si2O7 was obtained in activated mixtures at temperatures below 1400 degrees C. (c) 2005 Elsevier B.V All rights reserved.

AB  - Background/Aims: The aim of the study is detection and evaluation of the abdominal and gastrointestinal; infective foci using Tc-99m-ciprofloxacin (Laboratory for radioactive isotopes, Vinca). Methodology: In total 21 patients with clinical suspicion on abdominal or gastrointestinal infection were investigated. In all the patients, planar liver/spleen scintigraphy was performed. Ciprofloxacin chloride (3.5mg) was mixed with 555MBq of Tc-99m in 3mL of physiological solution and incubated for 20 min. After slow i.v. injection in a cubital vein, dynamic acquisition (1 f/min) was performed during the first 60 min in the position of interest, followed by static acquisition (500 000 imp) anterior and posterior view, abdomen and pelvis after 1 h and 4 h in all patients. When necessary, additional scintigrams were acquired after 24h. In all the patients with negative or equivocal findings of planar scintigraphy, emission computerized tomography (SPECT) was performed (60 positions, 6 degrees). Interpretation was made by three independent observers. Additional data were provided using clinical findings, ultrasonography, computed tomography and magnetic resonance imaging, laboratory analyses, and surgical or microbiological confirmation of infection. Results: There were eleven true-positive findings, seven true negative, two were false negative while one was false positive due to intestinal obstruction. Sensitivity was 79%, specificity 91%, positive predictive value 92%, negative predictive value 77% accuracy 84%. Conclusions: According to our results, scintigraphy with radiolabeled ciprofloxacin is a useful method for detection and assessment of exact localization of abdominal and gastrointestinal infections.

AB  - The low energy broad argon ion beam (1.35-2.0) keV was used for sputtering of a Ti target in an atmosphere of nitrogen gas to form TiN films. During deposition the growing thin film was under argon ion irradiation from the beam periphery. The influence of the ion beam energy (E-b) and average energy delivered by assisting ions to condensing film atoms (E-n) on TiN film properties was investigated. The titanium nitride thin films were deposited at a low working pressure of 1 x 10(-4) mbar and at ambient substrate temperature. XRD analysis revealed the formation of a delta-TiN phase with preferred (220) orientation for the stoichiometric composition of TiN films (RBS). The increase of both the intensity of the (220) peak and TiN film crystallite dimension with increasing the energy of Ti target bombarding Ar+ ions (E-b) was observed. By increasing the average ion energy per deposited metal atom (E-n) the (220) peak intensity and crystallite dimension decrease and a complete loss of (220) orientation at E-n close to 162 eV/at was found. In the range of E-n considered, the TiN films grain size decreases leading to the nanostructured surface as revealed by the STM analysis. The incident angle and energy of the assisted bombarding strongly influence the film-preferred orientation and sub-microstructure. (C) 2003 Elsevier B.V. All rights reserved.

AB  - Quenched and tempered samples made of plain carbon steel C 15 were salt bath nitrided at 580(0)C for 210 minutes and subsequently water quenched. The nitrided samples were half cut to obtain ail untreated surface that was polished before further processing. Both, salt bath nitrocarburized and untreated surfaces, were subjected to oxygen containing gas mixture glow discharge in the same bath. The plasma pulse power supply generated 16.6 kHz pulses with 0.95% duty cycle at a temperature of 480(0)C and pressure of 400 Pa for 60 minutes. The thickness of compound surface layer was measured by calotest method, while optical microscopy and SEM analyses were used to investigate the modified surface zone structure and morphology. The phase composition of obtained surface structure was analyzed by XRD. It was found that the salt bath treatment may produce the single epsilon phase or the single gamma zone on the plain carbon steel specimens depending on the active species concentration in the salt bath. The oxide layer phase formed depends on the applied surface pretreatment.

AB  - Pulse plasma oxidation of untreated, salt bath nitrocarburized and plasma nitrided/nitrocarburized samples made of hot work steel grade H11 was investigated. A continuous multi-step plasma processing was performed consisting of a half an hour plasma nitriding at 520 degreesC followed by 3.5 h nitrocarburizing at the same temperature and by a subsequent post-oxidation in a low current density H2O glow discharge during 45 min at 450 degreesC. The salt bath nitrocarburizing was carried out at a temperature of 580 degreesC for 210 min and was followed by the oil quench. In order to compare the oxide layer growth on the base material and on the epsilon-Fe-2(N,C)(1-x) layer, the salt bath treated sample. was half cut and plasma post-oxidized in a 80% H2O-20% H-2 glow discharge for 45 min at the temperature of 480 degreesC.

AB  - Duplex surface treatments of steel products are known to enhance fatigue strength, tribological properties, and corrosion resistance. In combined nitriding/coating deposition or nitriding/oxidation processes, a precise control of all steps of process parameters is necessary to get the required surface architecture. The process parameters are specific for different steel grades, which require detailed investigations and surface treatment of different steel-grade workpieces in separate charges. The samples made of steel grades AISI C 1045, 4140, and H 11 were salt bath and pulse plasma-nitrided, and untreated and surface treated samples were plasma-postoxidized. The Vickerss method was used for surface microhardness and depth profiling measurements, while the microstructure and surface zone morphology were examined by optical microscopy and scanning electron microscopy (SEM). The surface zone phase composition was analyzed by X-ray diffraction (XRD) method using CuKalpha radiation, and ball-grinding technique was used to measure the compound zone thickness. It was demonstrated that a low-friction, chemically stable, single-phase magnetite Fe3O4 superficial layer can be formed by plasma postoxidation of various steel-grade substrates in the same batch. Based on experiments performed on different steel-grade substrates, a source drain model was proposed to predict the phase composition of nitrided and postoxidized selected steel-grade samples.

AB  - The method and parameters of TiN film deposition processes are of dominant influence on the film growth microstructure and its physical properties. One of the PVD methods is the low energy ion beam reactive sputter deposition that offers the changes in the film properties by means of changing the beam parameters such as energy, divergence and current density. In this work, a laboratory made, broad beam, argon ion source was used for the reactive sputter deposition of TiN, thin films onto the glass substrates at ambient temperature. At constant argon beam energy (2keV), partial pressure of nitrogen (up to 6.6x10(-6) mbar), the substrate ion current and residual gas pressure were changed. The film deposition rate and thickness were controlled in situ by means of a light sensitive device placed on the rear side of the glass substrate. The physical properties of films: color, electrical resistivity and grain size, were correlated with the deposition parameters. High energy ion bombardment of growing film, relatively small ion to atom flux ratio up to 0.04, and low working pressure of 10(-5) mbar enabled the formation of a strong (220) preferred orientation rarely obtained for TiNx thin films.

AB  - Nickel films were deposited from a vapour phase (e-gun source) onto amorphous glass substrates at room temperature during a simultaneous bombardment with nitrogen ions at low pressure (4 x 10(-2) Pa). Under a constant partial pressure of nitrogen and negative substrate bias voltages the effect of bombardment intensity on the texture and morphology of Ni films (about 1 mu m) has been investigated by XRD and STM methods. The films under investigation exhibit a Variable degree of (200) preferred orientation by changing the ion to atom flux ratio (IAR) from 0.03 to 0.3. It was found that complete (200) texture was achieved for an IAR of about 0.1 and that further increase of IAR induces the decrease of preferred orientation. X-ray diffraction in combination with profiling by a 1 keV argon ion beam bombardment has been used for in depth texture and grain size analysis. It has been shown that oriented growth, grain size and morphology correlate with changes of bombardment intensity during the deposition as well as with the substrate bias potential.

AB  - TiN coatings were deposited in a single magnetron sputter ion plating system in balanced and unbalanced mode with a closed magnetic field configuration. The film microhardness, thickness, adhesion, microstructure, preferred orientation and topography were analyzed as a function of the substrate position inside the deposition volume. In the static deposition mode and under the limitations of the experimental set-up used, no real homogeneous deposition conditions were achieved, but a significant possibility of controlling the spatial distribution of deposition conditions was demonstrated. The variation of the coating microhardness over the target-to-substrate distance, d(S-T), ranging from about 80 to 210 mm was acceptable for practical applications, while the critical load for adhesive failure was found to decrease significantly with increasing d(S-T) in a balanced magnetron configuration. The variation of magnetic field configuration provided a relatively homogeneous distribution of the bias current density over the deposition volume, but the preferred orientation of the coating was changed from (200) to (111) with increasing d(S-T). The energy delivered per unit volume of growing film, S-E, and bombarding ion to deposited metal atom flux ratio j(i)/j(m) were considered. It was found that j(i)/j(m) can be used to describe qualitatively the change of preferred crystalline orientation of coatings. (C) 1998 Elsevier Science S.A.

AB  - Three operating modes of a single magnetron were used during deposition processes: balanced magnetron configuration with no external magnetic field and no bias potential applied (magnetron only), balanced magnetron configuration with permanent magnet cages positioned around the deposition volume to form a closed field configuration (BM mode) and an unbalanced magnetron closed field configuration (UBM mode). The influence of the deposition rate and ion j(i) to deposited metal atom j(m) flux ratio j(i)/j(m) at the substrate surface on the texture evolution was discussed. The deposition rate distribution over the target to substrate distance was found to depend on magnetic field configuration and also to be different in metallic and reactive mode. In UBM mode it was possible to obtain nearly constant bias current density along the deposition volume at the constant bias potential. The preferred crystalline orientation was changed from (200) to (111) by increasing target to substrate distance in both BM and UBM modes, while the film deposited in magnetron-only configuration preserved (111) texture.

abstract = "Three operating modes of a single magnetron were used during deposition processes: balanced magnetron configuration with no external magnetic field and no bias potential applied (magnetron only), balanced magnetron configuration with permanent magnet cages positioned around the deposition volume to form a closed field configuration (BM mode) and an unbalanced magnetron closed field configuration (UBM mode). The influence of the deposition rate and ion j(i) to deposited metal atom j(m) flux ratio j(i)/j(m) at the substrate surface on the texture evolution was discussed. The deposition rate distribution over the target to substrate distance was found to depend on magnetic field configuration and also to be different in metallic and reactive mode. In UBM mode it was possible to obtain nearly constant bias current density along the deposition volume at the constant bias potential. The preferred crystalline orientation was changed from (200) to (111) by increasing target to substrate distance in both BM and UBM modes, while the film deposited in magnetron-only configuration preserved (111) texture.

AB  - The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and deposition rate while the substrate temperature (ambient), partial pressure of nitrogen (3 x 10(-4) Torr) and substrate bias potential (4.5kV) were constant. The orientation and growth morphology change for films about 1 mu m thick were determined by XRD, SEM and STM method. The preferred orientation changes from (111) to nearly complete (200) as a function of ion to atom arrival ratio (IAR), and was independent of the substrate type (amorphous or monocrystalline). The ion beam bombardment of films after deposition enables the in depth determination of the nickel texture change during growth. For the highest IAR value the complete (200) texture was achieved at the beginning of deposition. The surface morphology (STM) and preferred orientation changes were correlated with ion to atom flux ratio and discussed on the basis of lowering the overall energy of the film.
