摘要：

Diamond films were coated on WC-Co alloy tool blades using a microwave plasma of CO-H2 mixed gas. Diamond film prepared at a CO concentration of 10% had good properties: Vickers hardness almost-equal-to 8500 kg mm-2 and adhesion force almost-equal-to 1.7 kg mm-2. No peel-off of the diamond film was observed after a cutting test of an Al-Si alloy rod at a cutting speed of 450 m min-1 for 0.5 h. It is thought that the high quality of the film originated from the selective etching of cobalt from the tool blade surface by CO-H2 plasma.
