Influence of H-2-N-2 atmosphere composition and annealing duration on the selective surface oxidation of low-carbon steels
(Corrosion Science, 2006)
The selective surface oxidation of the Ti-stabilized interstitial free (Ti-IF) and dual phase (DP) steel during recrystallization annealing at 820 degrees C under the variety of exposure time and composition of protective ...
Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
The role of sol-gel procedure conditions in electrochemical behavior and corrosion stability of Ti/[RuO2-TiO2] anodes
(Materials and Manufacturing Processes, 2005)
Using a sol-gel procedure, RuO2-TiO2 active coatings were formed on a titanium support. The conditions of preparation of the RuO2 and TiO2 sols were investigated and the sols were characterized by transmission electron ...
Synthesis of zirconia colloidal dispersions by forced hydrolysis
(Journal of the Serbian Chemical Society, 2006)
Different zirconia colloidal dispersions (sols) were prepared from zirconyl oxynitrate and zirconyl oxychloride solutions by forced hydrolysis. Vigorously stirred acidic solutions of these salts were refluxed at 102 degrees ...
Laser reflection spot as a pattern in a diamond coating - a microscopic study
(Journal of the Serbian Chemical Society, 2009)
Diamond coatings were deposited by the synchronous and coupled action of a hot filament CVD method and a pulsed CO(2) laser in spectro-absorbing and spectro-non-absorbing diamond precursor atmospheres. The obtained coatings ...
Influence of carbon concentration and rotational temperature on fullerene yield in RF reactor
(Materials Science Forum, 2006)
In this paper, report on fullerene formation in a radio-frequency (RF) thermal plasma reactor has been presented. In order to determine the degree of evaporation of the graphite precursor used, analysis of SEM micrographs ...
Electrophoretic Deposition of Biocomposite Lignin/Hydroxyapatite Coatings on Titanium
(International Journal of Chemical Reactor Engineering, 2009)
In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified ...
Damage of Ti-stabilized interstitial free steel by gas corrosion
(Kovove Materialy = Metallic Materials, 2008)
Degradation of Ti-stabilized interstitial free steel and damage of this steel caused by selective oxidation during 60 s of recrystallization annealing at 820 degrees C under the different compositions of protective H(2)-N(2) ...
Synthesis of sillenite-type compounds from zeolite precursors: XRPD and SEM/EDS analyses
(Journal of Optoelectronics and Advanced Materials, 2008)
The paper analyze the possibility of using LTA zeolite as a precursor for obtaining sillenite phase (Bi(12)MO(20), M=Si, Ti, Ge) by hydrothermal synthesis process. The synthesis procedure involves mixing of zeolite (Na-LTA) ...
Surface structures formed on AISI 420 stainless steel by pulsed laser irradiation
(Materials Science Forum, 2005)
The effects of TEA CO2 laser radiation on AISI 420 stainless steel and formed surface structures are studied. The laser energy density of 45.0 J/cm(2) has modified the target surface. Qualitatively, the modifications of ...
