Research output: Contribution to journalArticle


Results from tribotechnical testing of WC-Hadfield steel hard alloy pins rubbed against tool steel disk at normal load of 550 N and at sliding friction velocity in 0.65-2.8 m/s range are presented. Microstructure of surface layers after testing has been investigated. As is shown, phase composition and topology of friction surface are functions of the sliding speed value.
