Study of Wear Resistance of Sintered Powder Tool Materials

Abstract

The purpose of the studies presented in this paper was to improve cutting properties of tool made of powder metal high-speed steel due to controlling the conditions of friction on contact areas of edgetools at cutting temperatures. Control of friction was carried out on the basis of alloying steel with 5% aluminum oxide (Al2O3), introducing 2% additive agent BN, and that allowed forming stable high-strength secondary structures, significantly extending the intervals of material self-organization. The use of both variants in alloying steel with 20% additive agent TiCN allowed significantly increasing lifetime of tool made of powder metal high-speed steel.
