STUDY OF WEAR BEHAVIUR AND COATING QUALITY OF ZINC AND CHROMIUM METALLIC COATING ON MILD STEEL SUBSTRATE

In order to provide protection to substrate and increasing substrate material
properties, coating is introduced to industry to increase working efficiency and also for
economic advantage. There are lot of type of materials used for coating in industry such
as zinc, nickel and chromium. In short, this study was conducted to analyze the adhesion
and wear behavior of metallic coating using zinc and chromium on mild steel substrate by
varying the coating thickness. The coated mild steel sample then will go through several
laboratory evaluations such as, friction and micro hardness test. The result from the tests
was compared and analyzed. It was found that harder material with smooth surface
increased the adhesion strength and wear resistance.
