Abstract
Running-in process is important for sliding parts of machines, because it has an influence on friction and wear properties of the sliding materials. However, the running-in behavior is not clarified quantitatively well. Especially, it had not been done about DLC films at all. In the present work, we investigated the correlation between friction coefficient and the number of wear particles in running-in process by using the online particle counter. And then, we compared sliding distance of completion of running-in judged by the particle counter with it judged by friction coefficient. As a result, the running-in process behavior of DLC film was clarified.
