ANALYSIS OF THE HARD-FACED MULTI-PHASE MATERIAL WEAR PROCESS BY THE BALL-CRATERING METHOD

Abstract

This paper presents the results of tribological testing performed on multi-phase layers produced by the hard-facing method. Three materials based on Fe-C-Cr alloys and containing carbide-forming elements B, V, Nb, Mn, Mo and W, used to hard-face abrasion-resistant layers, were selected for the study. The ballcratering method performed the tests in two variants: with or without an abrasive slurry. The obtained results demonstrated that all test materials showed similar wear intensity in the presence of abrasive slurry, while the wear intensity varied for the test with no abrasive slurry.
