DLC (diamond-like carbon) films are one of the best candidates as anti-wear coatings for high performance mechanical elements and electric devices that require tribological enhancement and chemical stability. Most of previous researches on DLC films were concerning with DLC film itself or its properties. However, tribological characteristics of DLC film should be affected by properties of mating materials. In this paper, four kinds of mating balls were prepared for tribological tests of DLC film. The mating balls were made with same material (stainless) but apply different annealing conditions. The effect of hardness of mating material on friction and wear of DLC films has been measured with precision friction tester. Testing results shows, the harder the mating materials, the lower the friction coefficient and wear rate among results of martensite balls. The reason of high friction coefficient in soft mating materials considers as widen the contact area during experiment. It can be proved by measuring wear profiles on DLC films and wear trace on mating balls.
