The Zn-Ni-TiO2 composite coatings were developed on mild steel by electrodeposition method. The bath constituents (ZnSO4.6H2O, NiSO4.6H2O, TiO2, thiamine hydrochloride) and operating conditions (temperature and pH) were optimized by Hull cell method, for peak performance of the coating against corrosion. The coatings were prepare...

Hydrogen peroxide as an oxidant agent was used for desulfurization of a petroleum hydrocarbon fraction (C10-C22) with boiling range of 175-375 ℃, (light fuel oil) in the presence of acetic acid as catalyst. The oxidation was performed in an ultrasonic bath. It is found that increasing the amount of hydrogen peroxide lead to increase the oxidation rate and so desulfurizatio...

The electroless deposition method was used to prepare Ni-based nanocomposite coatings, this approach represents an alternate way of having coatings on the different substrates. Most previous literatures subject and work deals with a study effect process conditions and, Bath composition microstructure at macroscale Ni-Al2O3 composite coatings. Though, step structure bath are little, present aims...

Abstract Fe–Ni invar alloy (Fe 64–Ni 36 wt%) has a very low coefficient of thermal expansion (CTE) than any other metals. For this reason, it been used as fine metal mask (FMM) in RGB patterning OLED manufacture process. However, the resolution display is getting higher, thickness FMM thinner and then conventional extruded sheet cannot be directly. The electrodeposition can alternative for fabr...
