Summary

Ti-containing diamond-like carbon (DLC) film was developed with an unbalance magnetron sputtering method and its tribological behavior was compared with a pure DLC film. The friction coefficient was investigated using a pair of cam and follower in a direct acting valve train of the internal-combustion engine. The friction coefficient of the Ti-containing DLC film (μ =0.05) was substantially lower than that of the pure DLC film (μ =0.10). A secondary ion mass spectrometric analysis (SIMS) clarified that the amount of the extreme pressure agent adsorbed on the sliding surface of the Ti-containing DLC film was larger than that on the pure DLC film suggesting that this caused the lower friction.
