| Summary: | This work is devoted to the problem of developing
technological operations aimed at improving the structure
and properties and, as a result expanding the scope of metalcutting inserts from tungsten-free hard alloys. The search
for alternative analogues of traditional tungsten-cobalt
hard alloys is an urgent task of modern materials science,
due to the high cost and shortage of their components.
In this paper, we study the effect of a continius ion beam
on the change in the morphology, mechanical properties,
and performance characteristics of metal-cutting inserts
made of tungsten-free hard alloy grade KNT16 (TiCN-NiMo). It has been found that the effect of continuous ion
beams leads to a significant change in the wear resistance
of cutting plates during turning operations on mediumcarbon steel 40KhN. A rational composition of the ion
beam has been established, in which the cutting plate is
subjected to the least wear after completion of the test
cycle. Using the methods of scanning electron microscopy
and scanning probe microscopy, a study of the microrelief
and morphology of the surface of the samples is carried
out. |
