APPARATUS FOR MECHANICAL WORKING OF HARD MATERIALS Russian patent published in 2002 - IPC

Abstract RU 2178013 C2

FIELD: mechanical engineering. SUBSTANCE: apparatus has base and working part secured in base. Working part is made of hard alloy containing tungsten monocarbide, solid tungsten-in-titanium carbide solution of (Ti, W)C phase and cement cobalt bond. Surface layer of working part having thickness of 3-15 micron is made of material enriched in tungsten monocarbide with concentration of this material reaching 50-99.5 wt%. Apparatus is used for cold and hot mechanical working of different materials, preferably metals and alloys and may be formed as cutter, drill, spinneret etc. Apparatus may be employed under impact load conditions. EFFECT: simplified construction, wider operational capabilities and prolonged service life. 1 dwg, 1 tbl
