If it is not done correctly, serious problems such as machine seizure may occur. Diamond-like carbon (DLC) films are used in various fields as an excellent tribo-material because of their low friction coefficient and high wear resistance. However, their running-in behavior has not been clarified quantitatively in detail. In addition, previous studies have not adequately investigated changes in wear particles during the running-in process. In the present work, we investigated the correlation between the friction coefficient and the number of wear particles during the running-in process using an online particle counter. Then, we compared the sliding distance at the completion of running-in judged using the particle counter with that judged using the friction coefficient. As a result, the running-in behavior in the combination of a DLC film and AC8A Al alloy is well clarified. In the case of a DLC/AC8A sliding pair, the DLC surface showed no significant changes after wear tests. The AC8A surface became smooth by abrasion and plastic deformation during running-in, and the ratio of silicon occupying the surface area increased slightly.}, title = {Running-in Behavior in the Combination of Diamond-like Carbon Film and AC8A Aluminum Alloy}, year = {2018} }
