Tribological Characteristics of Soft/Hard Coating for High-Speed Rotating Machine Elements

고속회전 하는 정밀부품을 위한 연질/경질 코팅의 트라이볼로지적 특성에 관한 연구

Recently, rotating elements which use mechanical and electrical systems have been utilized for high speed and accuracy to increase the performance. The most important thing to get a more reliable system is to understand the friction, wear and characteristics which has an effect on various coated surfaces. In this study, the tribologicali characteristics of various soft/hard materials were investigated by using a custom-built pin-on-reciprocator tester From the experimental results, it was found that the friction coefficients of the soft material coated surfaces were lower under various normal loads due to trier self-lubricating ability and material transfer to the counter surface.
