Friction and wear property improvement by surface modification: effect of electroless plating films and DLC coating

摘要

In this study, we examined the improvements in friction and wear properties between steels for aircraft parts, resulting from the surface modifications with electroless plating film and amorphous carbon coating or diamond-like carbon (DLC) coating. Friction and wear properties are measured using a pin-on-flat wear-testing machine with reciprocating sliding. From measurements of the coefficient of friction and wear amount, observations during sliding motion and visual inspection of wear traces, the following was clarified. A remarkable improvement of friction and wear properties is realized by DLC coating. Electroless plating increased the hardness of the plated surface considerably. However, it does not contribute to improved friction and wear properties.
