摘要

FIELD: ceramic compositions. SUBSTANCE: compacted fine-grained ceramic composition is based on titanium diborate with presence of wolfram and cobalt. Composition is used in the capacity of cutting tool, in particular, for machining of titanium alloys at high speeds. Cutting plate has cutting edge limited by front and rear surfaces. EFFECT: improved operational characteristics of cutting tool. 27 cl, 6 dwg , 4 tblt
