Study of Wear Resistance of Sintered Powder Tool Materials
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.
