- - MANUFACTURING METHOD OF TUNGSTEN-TITANIUM CARBONITRIDE AND SINTERED TUNGSTEN-TITANIUM CARBONITRIDE PREPARED THEREBY
An aspect of the present invention provides a manufacturing method of sintered titanium carbonitride-tungsten (TiCN-W), comprising: (step 1) a step of manufacturing a mixture of titanium oxide (TiO_2) powder, tungsten oxide (WO_3) powder, and carbon powder; (step 2) a step of grinding the mixture; (step 3) a step of performing thermal treatment of the ground mixture; and (step 4) a step of performing spark plasma sintering of the mixture for which thermal treatment is performed. According to an aspect of the present invention, the sintered titanium carbonitride-tungsten made by spark plasma sintering has a higher hardness and a greater toughness than those of an existing sintered titanium carbonitride (cermet) due to evenly dispersed tungsten.
본 발명의 일 측면은, 티타늄 산화물(TiO) 분말, 텅스텐 산화물(WO) 분말 및 탄소 분말을 혼합한 혼합물을 제조하는 단계(단계 1); 상기 혼합물을 분쇄 처리하는 단계(단계 2); 상기 분쇄 처리된 혼합물을 열처리하는 단계(단계 3); 및 상기 열처리된 혼합물을 스파크 플라즈마 소결(spark plasma sintering) 처리하는 단계(단계 4);를 포함하는 탄질화티타늄-텅스텐(TiCN-W) 소결체 제조방법을 제공하고, 본 발명의 일 측면에 따르면, 스파크 플라즈마 소결(spark plasma sintering) 처리로 제조된 탄질화티타늄-텅스텐 소결체는 고르게 분산되어 있는 텅스텐 상으로 인하여 종래 탄질화티타늄계 소결체(서메트) 보다 높은 경도와, 준수한 인성을 갖는 특징이 있다.
