Abstract

The study considers some of the methods to impact the friction conditions in cutting of metals through alloying HSS-based sintered powder tool materials of modern generation. The first method involves the reduction of self-organization level through the reduction of the friction coefficient at operating temperatures by addition of 5% aluminum oxide (Al2O3). The second method is based on the modern concepts of tribology on the possibility to extend a range of self-organization through stable high-strength secondary structure appearing on the surface of the tool. This is achieved by addition of 2% BN (hexagonal). The use of both methods makes it possible to significantly increase the tool life, and it is achieved by addition of 20% TiCN.
