Improving Durability of Cermets for Metal Cutting by Generation of Subsurface Multilevel Structures

Abstract:

Experimental data on studying structural-phase states developed in the subsurface of TiC/Ni-Cr-Al alloy cermet under condition of superfast heating and cooling produced by pulse electron beam melting have been presented in this paper. The effect of the surface structural state multimodality on the temperature dependencies of friction and endurance of the cermet tool in cutting metal has been investigated. The effect of structural states on the cermet’s properties consists in improving its endurance for cutting metal by a factor of 20.
