Abstract

Zinc based coatings modified with aluminium and tin inclusions were electro deposited in chloride zinc sulfate electrolytes containing a metallic powder of titanium.It was found that presence of these particulates is suitable to obtain Zn AI Sn-Ti composites coating that could help in crease the micro hardnesss characteristics and wear properties. The hardness and wear properties of the deposited coatings were examined with diamond base micro-hardness tester and CETR reciprocating sliding tester respectively. The structural properties were examined with the help of scanning electron microscope.lt was observed that structural coating surface impact on the hardness propagation with increases from 33.4 to 299 kgf mm-~(HVN4o),and shows a considerably higher wear resistance from 2.351 g/min to 0.002g/min. lt is obvious that plastic deformation of the working steel structure is dependent on protective coating and the concentration of the individual particulate.
