The high polymer material, Polycarbonate (PC) was coated with DLC (Diamond Like Carbon) noticed as a hard film. PC has many excellent characteristics. DLC was coated by following 2 types processes (P-CVD/DLC/PC & IVD/DLC/PC), (1) Plasma-chemical Vapor Deposition (P-CVD) (2) Ionic Vapor Deposition (IVD). Therefore, it is the research purpose that the evaluations of tribological properties for surface modified PC were experimentally carried out. From the experimental result, the friction evaluation shows that DLC coated PC markedly reduce the friction coefficient and wear compared to Virgin (uncoated) materials. Especially, IVD/DLC/PC had low friction coefficient and high adhesion further than P-CVD/DLC/PC. However, when film thickness was increased, as for IVD/DLC/PC, the friction coefficient rose in the early stage, and P-CVD/DLC/PC maintained the low friction coefficient.
