Diamond like carbon thin film is widely studied and well known due to its excellent mechanical hardness and low friction coefficient performance. In this study, the nano-hardness and friction coefficient of non-doped DLC and Si-doped DLC coated on UIC60 steel were investigated. The results show that Si-doped DLC sample perform better than non-doped DLC sample in term of higher hardness and lower friction coefficient. Besides, the film thickness and Raman spectroscopy of both DLC sample were also investigated. As for both of the DLC coated sample, the SEM images showed a better resulting surface with mild fatigue crack and less wear fragment confined in the wear spot.
