Abstract

A three-step process to produce wear-resistant, composite diamond coatings is presented. Diamonds are deposited by RF thermal plasma CVD, reinforced by an electroplated metal binder, and regrown to form a continuous film. Microscratching and pin-on-disk wear tests indicate that the three-step composite films are more adherent than plasma deposited diamonds alone.
