Abstract
In this study, while the abrasive plates for diamond have been prepared through mechanical alloying and sintering of elemental powders, a fabrication route of plasma thermal coatings has been adopted for the first time. When diamond knife is sharped or polished, a metal plate has been applied, which is made of mechanical alloying and sintering. In this study, in order to develop a cost - effective manufacturing process, plasma coatings of FeCrNi and Ti on cast iron plate were applied together with Al intermediate layer coatings. The plasma coatings were successfully performed, and the optimum coating layer conditions were discussed in terms of micro-structural observations at the interfaces.
