| Research Abstract |
The diamond thin films were produced onto pure titanium and mild steel substrates by micro wace plasma CVD.The diamond like carbon films were coated onto tool steel and cemented carbide by ion plating. For diamond thin films, the adhisive strength was measured by scrach testing machine. The adhesive strength increased with increasing the film thickness. For diamond like carbon films, the adhesive strength, hardness and friction and wear properties were mesured. The hardness was almost coincident with that of diamond film. The adhesive strength was about 40 N.The friction was less than 0.15. The wear properties was improved by coating diamond thin films.
