WEAR RESISTANCE OF CUTTING TOOLS COATED FROM HEAT-RESISTANT, CHROME ALLOYS
Keywords:
high-speed cutting tool, electron-beam processing, combined surface treatment.Abstract
In this article, a comprehensive study of the effect of surface treatment with low-energy electron beams on the structural and phase composition of the surface layer of a high-speed cutting tool, as well as on the microhardness and wear resistance of disk cutters, was carried out. The surfaces of high-speed tools made of R6M5 alloys, heat treated with nitriding, coated with a layer of NbHf alloy deposited by magnetron sputtering, are modified by electron beam processing. As a result, an interlayer is formed with the concentration of alloying elements, which gradually varies in depth. The results of the study of this composite using X-ray diffraction analysis are presented.
