Abstract

The deposition mechanism of diamond film on cutting tools and the state of the interface between film and substrate are studied theoretically and experimentally. Methods for controlling diamond crystalline state and improving adhesion of diamond films to substrates are proposed to improve the quality of diamond-coated tools. Experiments are performed by cutting Al-Si18% alloy and SiCp/Al composite with diamond coated tool. The results indicate that the life of coated tools is 90 times higher than that of non-coated tools. Wear mechanism of diamond-coated tools is also studied.
