Изобретение относитс к составу керамического материала, который может найти применение в инструментальной промышленности (резцы, фрезы, сверла, абразивные круги), а также в машиностроении (торцовые уплотнени , конструкционные узлы).The invention relates to the composition of a ceramic material that can be used in the tool industry (cutters, cutters, drills, abrasive wheels), as well as in mechanical engineering (mechanical seals, structural units).
Известен керамический материал, включаюший нитрид кремни и окись магни 1Ceramic material is known, including silicon nitride and magnesium oxide 1
Наиболее близким к изобретению вл етс керамический материал, включающий нитрид кремни , карбид металла (кремни ), окись магни или окись алюмини 2J.Closest to the invention is a ceramic material comprising silicon nitride, metal carbide (silicon), magnesium oxide or 2J alumina.
Недостатком вышеуказанных материалов вл ютс невысокие значени твердости и износоустойчивости.The disadvantage of the above materials is the low values of hardness and wear resistance.
Целью изобретени вл етс устранение этих недостатков, т. е. повышение твердости и износоустойчивости материала.The aim of the invention is to eliminate these disadvantages, i.e., increase the hardness and wear resistance of the material.
Поставленна цель достигаетс тем, что керамический материал содержит в качестве карбида металла карбид титана при следуюшем соотношении указанных компонентов (в вес. %):The goal is achieved by the fact that the ceramic material contains titanium carbide as a metal carbide with the following ratio of these components (in wt.%):
Нитрид кремни 55-90Silicon Nitride 55-90
Карбид титана5-30Titanium carbide 5-30
Окись магни илиMagnesia or
Окись алюмини 5-15.Aluminum oxide 5-15.
Дл получени керамического материала нитрид кремни в количестве 72 вес. % карбид титана - 17 вес. % и окись магни (окись алюмини ) - 11 вес. % подвергают совместному размолу и смешиванию в твердосплавном барабане в среде ацетона, Высушенную смесь подвергают гор чему прессованию в графитовой прессформе с карбидкремниевыми пуансонами при температуре 1700 С, давлении 4ОО кг/см и времени выдержки 30 мин. Полученный материал имеет твердость Н R А 94 кг/мм , износоустойчивость по задней грани резца (0,4 мм) 80-22О мин.To obtain a ceramic material silicon nitride in the amount of 72 weight. % titanium carbide - 17 wt. % and magnesium oxide (alumina) - 11 wt. % is subjected to joint grinding and mixing in a carbide drum in acetone, the dried mixture is hot pressed in a graphite mold with silicon carbide punches at a temperature of 1700 ° C, pressure 4OO kg / cm and holding time 30 minutes. The resulting material has a hardness of H R A 94 kg / mm, wear resistance on the rear edge of the cutter (0.4 mm) 80-22 O min.
