The fundamentals of synthesis of modified layers on cutting-tool hard alloys

Abstract

A methodology has been elaborated for controlling the structure formation in cutting-tool hard alloys during the plasma modification of their surfaces in order to produce an ultradispersed structure in the surface layer providing a high level of performance characteristics. The paper presents a block diagram of synthesis of modified layers with an ultradispersed structure, which includes a combination of theoretical, experimental, and technological investigations. The tool life testing of the modified tools has been carried out.
