Phase transformations in hard alloy in friction and evaluation of fractal characteristics of friction surfaces

Research output: Contribution to journalArticle

Abstract

The results of tribotests of hard alloy WC - Hadfield steel when rubbing against tool steel under load 550 N and sliding velocity 0.65-2.8 m/s are presented. The microstructure of the hard-alloy surface after testing has been investigated. It was found that phase composition of the surface layers and topography of the friction surface in a pin-on-disc couple depend on sliding velocity.
