Abstract

Diamond-like carbon (DLC) coatings, especially hydrogenated DLC coatings (α-C:H), are known for their excellent tribological properties such as small friction coefficients (0.05~0.2) and wear rates (<10-15 m3/N·m) [1, 2]. However, the hardness of α-C:H films are typically less than 20 GPa. While TiAlN coatings are known for its high hardness, but the friction coefficient of TiAlN, especially under dry conditions, is quite large reaching 0.9-1.0 at room temperature and 1.5 at 400 ℃ [3]. Multi-layered coatings can combine the advantages of the constituent layers and are preferred to enhance integrated performance over single-layered coatings.
