The DLC film deposited at substrate temperature of 100℃ shows the best integrated property with carbon content of sp〓 bonding state up to 40% which is two times more than that in the films prepared by Americans with the same method. Accordingly, the microhardness is up to 30Gpa, and friction coefficient and optical band gap decrease to 0.10 and 1. 76eV respectively. It is found that sp〓C content in DLC films decreases with the increasing substrate temperature in the process of film deposition, especially after 300℃.
