Abstract
The roughness of the friction surface of antifriction carbons used in sliding friction units lubricated with water affects the tribotechnical characteristics during the running-in process. This article experimentally substantiates the range of optimal surface roughness formed during mechanical cutting of carbon plastics in terms of tribotechnical efficiency. The results of a series of tribotechnical tests using various methods under various conditions (contact pressure, sliding speed, counterbody materials) are presented. The relationship between the initial roughness and the effectiveness of a running-in coating based on FORUM® polytetrafluoroethylene powder is established.
