Fabrication and Application of CVD Diamond-Coated Copper Wire Drawing Die
To improve the surface quality and adhesion of diamond film is the key factors to realize CVD diamond coating widely applied in the wear-resistance parts field. Through optimizing deposition process parameters, the article used the straight wiredrawing chemical vapor deposition to depose the diamond film in the bore surface of WC-CO carbide wiredrawing mould. The surface topography of the coating, film quality and surface roughness were detected and the preparation of CVD diamond film coated wire drawing mould in drawing copper wires production line was applied. The experimental results show that working life of diamond film coated wire drawing mould improved to 40~ 50 of that traditional hard alloy mould, and the controlled copper wire had the better precision and surface quality.
