The wear properties of a-C:H and SiDLC in pressurized high-temperature water were investigated. We conducted friction tests for DLC pins in pressurized (10 MPa) high-temperature (23, 100, 200, 300 oC) water with two different amounts of dissolved oxygen (0.5, 40 mg/L) to figure out the wear properties of DLC in an oxidative environment. We then clarified that (i) Si-DLC shows great wear resistance even in 300 oC, 10 MPa water with 40 mg/L dissolved oxygen, (ii) while wear scar of a-C:H has soft structure-changed surface, wear scar of Si-DLC has relatively hard surface without much structural change.
