THE INFLUENCE OF PRELIMINARY TREATMENT OF HARD-ALLOY TOOL BY HIGH-INTENSITY PULSED ION BEAMS ON STRUCTURE AND WEAR RESISTANCE OF DIAMOND COATING

摘要

Preliminary high-intensity ion influence allows to one create an alloyed coating layer of tungsten carbide on the cutting coating of a hard-alloy wood-working tool. As a result the diamond coating formed from glow-discharge plasma does not have a preferred direction of growth, and mechanical stresses and adhesion strength of diamond coating increase. The edge wear of modified tools is noticeably decreased during the cutting of woody materials.
