Three types of DLC films, pure DLC, F-containing DLC, and Si-containing DLC film, were deposited on a WC-Co substrate by a plasma-enhanced CVD technique. Friction and wear properties were determined using a ball-on-plate type reciprocating friction tester in water, comparing the water results to those in ambient air. The friction coefficient of DLC and F-DLC films in water was considerably lower than that in air. With Si-DLC, the friction was almost the same level in both water and air, and was less than 0.1. The specific wear rate of films in water was much smaller than that in air and varied around the low level of (10)^<-8>-(mm)^3/Nm in water. With DLC and F-DLC films, the transferred amount of material on the friction surface of a mating ball was larger in a water environment than that in air. With a Si-DLC film, the difference in the transferred amount when exposed to either the water or air environment was small.
