Formation of Nano-Sized Structural-Phase States in Surface Layers of a Cermet Alloy and the Influence of the States on the Tool Life of Cermet Plates in Metal Cutting

Abstract:

A comparative analysis of the surface-layer microstructure of a tungsten-based cermet alloy modified with pulsed high-energy electron beams generated by gas-discharge plasmas and of the tool life of metal-cutting plates prepared from this alloy is performed. The choice of a plasma-forming gas providing for the emission of electrons out of the plasma-filled cathode is shown to have a profound influence both on the formation process of nanosized structural-phase states in the surface layer of the cermet alloy and on the tool life of the metal-cutting plates prepared from this alloy.
