Abstract
The tribological behaviour of composites, particularly in contact with steel, is to be estimated as relatively weak. As a promising improvement, the application of modern coatings is considered. In this context, the results of frictional and wear investigations of carbon fibre reinforced epoxy and polyethersulfone as well as glass fibre reinforced polypropylene composites in contact with coated and uncoated steel 100Cr6 are presented. The coating consists of diamond-like carbon (ta-C) layer. A remarkable outcome of the study is the substantial decrease of the specific wear rate of the investigated material pairings by the application of carbon coated metal. The tribological system, which is responsible for the excellent tribological characteristics, is determined by predominantly sliding w ear and suppressed abrasive wear.
