Abstract

본 발명은 세라믹이 코팅된 Al2O3-TiC계 절삭공구는 TiC, Al2O3를 주성분으로 하여, TiO2, WC, Y2O3, MgO, ZrO2, Mo2C를 첨가물로 하는 소결체이며, TiC와 Al2O3가 각각 20 내지 80중량%, 첨가물은 각각 0.1 내지 5중량%의 원료 혼합물로 구성된 것을 코팅용 모재로 하고, 상기 모재의 표면에 화학 증착법으로 금속 결합층을 코팅하고, 그 다음에 중간층을 코팅한 후, 표면을 세라믹 내마모층으로 코팅하여서 제조한다.
본 발명에 따른 방법에 의해 제조된 절삭공구는 금속결합층과 중간층의 형성에 의해 내충격성이 증진되고, 화학 증착법에 의해 코팅이 이루어지므로 기존의 절삭공구 보다 수명이 길며, 충격흡수성이 강하고 공구 전체의 파손이 방지될 수 있는 등의 절삭성능이 개선된 효과를 나타낸다.
