Modification of metal-cutting plates from tungsten-free hard alloy grade KNT16 by continuous ion beams by A. M. Badamshin, S. N. Povoroznuyk, V. V. Akimov, E. A. Rogachev, A. A. Krutko

“…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. …”
