AB  - In this paper the morphology (SEM analysis), the internal structure (cross-section analysis) and the growth mechanism of Ni and Co powders electrodeposited from ammoniacal electrolyte are investigated. It is shown that morphology and the internal structure of those powders are quite different. For Ni powder, all particles are of the same morphology, cauliflower-like type. In the case of Co powder, generally two types of particles are detected: (1) dendrite particles and (2) different types of agglomerates, compact, spongy-like and ball-like ones. The growth mechanism for all agglomerates is based on the fact that with the time of growth the disperse (dendrite) agglomerate is branching in different directions and at the tip of each branch spherical diffusion takes over the planar one, providing conditions for the growth of compact deposit. After some time, these branches form compact deposit all over the agglomerate surface and the same agglomerate further grows as a compact one, until it falls off from the electrode surface. Characteristic of all agglomerates is the presence of deep cavities on their surface and the fern-like dendrites on the bottom for most of these cavities.

AB  - The apparent density and flowability of copper powder are related to the structure of powder particles and the reversing current (RC) regimes. It was shown that the apparent density of the powders increases with the increase in the compactness of particles, hence with the increase in the frequency of RC and with the decrease in the cathodic to anodic time ratio.

AB  - The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, which does not allow the particles to jam and hence permits the free flow of nonsieved powder. It was also shown that the representative powder particle, the elementary cell of which can be presented by a 3D-cross, describes the properties of the powder relative to its flowability well.

AB  - Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified polyglycol ether, PEG 6000 and 3-mercaptopropanesulfonate. The zinc coating was electrodeposited from a sulfate solution in the presence of a dextrin/salicylaldehyde mixture. They were examined by STM and X-ray diffraction analysis, and measurements of the reflection of light from their surfaces were taken. The mean sizes of atomically flat parts of these surfaces were estimated by the STM software measurements, using options for the determination of the autocovariance function and the power spectral density function. It was shown that the mean sizes of atomically flat parts of the copper coatings were several times greater than the mean size of atomically flat parts of the zinc coating. This difference probably leads to the difference in the maximum degrees of mirror reflection between copper and zinc coatings.

AB  - A method for the improvement of the printing properties of offset printing forms is presented. Specimens of technical aluminum were electrochemically roughened and treated in different alkaline solutions of chromium chloride in order to chemically deposit a chromium layer. The composition of the surface layer was investigated by EDAX Chromium was found on the specimens that had been treated in an alkaline solution of chromium chloride. while no chromium was found on chemically untreated specimens or on specimens that had been treated in an alkaline solution without chromium chloride. The spectral reflectance from treated and non-treated specimens was also measured. The chromium-treated specimens were brighter than the non-chromium-treated ones. The wettability of the chromium-treated samples was compared with the wettability of the non-chromium treated samples by measuring the contact angle with water and the wetted area. The chromium-treated samples showed increased wettability compared with the non-chromium-treated samples. A printing test was performed under real printing conditions. Control prints was analyzed densitometrically and statistically. The chromium-treated printing forms gave clearer prints than the non-chromium-treated printing forms under all printing conditions.

AB  - In this work, the structure of a silver mirror surface was examined by the STM technique. It was shown that the Structural characteristics which enable a high degree of mirror reflection from this surface, which is very close to the ideal reflectivity of silver, are: flat and mutually parallel parts of the surface which are smooth on the atomic level, and distances between adjacent flat parts which state several atomic diameters.

AB  - In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents were examined and compared with the structure of a silver mirror. It was shown by the STM technique that the structural characteristics important for the mirror brightness of the copper surface polished both mechanically and electrochemically and the copper coating are: (1) flat and mutually parallel parts of the surface which are smooth on the atomic level and (2) distances between adjacent flat parts are comparative with the distances between the adjacent flat parts of a silver mirror. Also, on the basis of the STM analysis, a mathematical model treating brightness from the point of view of geometrical optics was developed. X-ray diffraction analysis of the copper surfaces showed that mirror brightness is not associated directly with the degree of preferred orientation. (C) 2001 Elsevier Science B.V.

AB  - Aluminum as the base of offset printing plates should make good contact with wetting agents and the light sensitive layer and should be resistant to wear and cracking. In order to achieve this, the aluminum is roughened and eventually anodized. A thin, electrochemically deposited chromium layer is used as the non-printing element in bimetallic offset printing forms. Chromium shows excellent wettability and wear resistance. The possibility of chemical deposition of chromium on aluminum from an alkaline solution is examined in this paper The presence of chromium was confirmed and measured by EDAX. A difference in the spectral reflection characteristic between chromium-treated and non-treated specimens was also detected. An influence of a chromium layer on an aluminum surface was examined by water drop spreading. Chromium-treated samples showed better wettability than non-treated samples, but they are less wettable than anodized samples.

AB  - The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by scanning tunneling microscopy (STM). The silver was electrodeposited under current controlled electrochemical conditions at 26 mu A/cm(2), which corresponded to a deposition rate of 0.1 monolayers (ML) per second. For comparison, physical deposition of Ag on HOPG was performed by DC Ar+ ion sputtering, at the same deposition rate and for the same deposition times. In both cases, Ag grows in an island growth mode, but the distribution of the islands appears to be quite different. In physical deposition, the Ag islands are almost homogeneously distributed over the substrate surface and a slight accumulation of islands on steps does not contribute significantly to the overall morphology. This indicates the crucial role of point defects on the substrate in the initial stages of nucleation. In electrochemical deposition, more lined defects are observed after a flow of current, and their role in the beginning of the nucleation is more pronounced. Lined defects are responsible for the string-like shaped domains of deposited atoms. Also, the existence of string-like shaped nucleation exclusion zones is indicated. The problem of the formation of nucleation exclusion zones, which appear only in electrochemical deposition, has been reconsidered and a new explanaton of their formation is given. A mathematical model for the calculation of the radius of the nucleation exclusion zone has been developed.
