Diamond like carbon (DLC) coatings were deposited on PPS by RF plasma CVD method. The properties of DLC coatings were investigated by Raman spectroscopy, hardness test and friction-wear test. With increasing the RF power, the hydrogen content in DLC coating is decreased, obtained from comparing gradient of the base line of the Raman spectrum, and the hardness is increased. The hardness of DLC coating is from 8 to 15 times higher than that of non-coated PPS. DLC coatings can decrease the friction coefficient in the range of 0.15 to 0.3. The friction coefficient of DLC coating depends on not the,RF power but the sliding partner. DLC coatings decrease the specific wear rate to one tenth to non-coated PPS.
