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.
