ADHESIVE WEAR BEHAVIOUR OF CARBIDE COMPOSITES AND TOOL STEELS

摘要

Tallinn University of Technology, Ehitajate tee 5, 19086 Tallinn, Estonia Abstract: Abstract: The performance of hard alloys - carbide composites and tool steels (of different composition and structure) in the conditions of prevailing adhesive surface failure (complemented by SEM studies) was investigated. It was shown that hardness does not enable us to estimate wear resistance of alloys exactly. In respect to adhesive wear resistance, TiC-base cermets with a steel binder and high alloyed tool steels can compete with WC-base hardmetals.
