Abstract

본 발명은 내마모성, 내열성 및 내부식성을 필요로 하는 절삭 공구에 관한 것으로, 특히 서메트(Cermet) 또는 초경합금이 기본 모재인 드로우어웨이 인서트(Throvavay Insert)에 고경도물질을 피복하여 선삭 또는 밀링가공용 절삭공구로서 우수한 성능을 발휘할 수 있는 표면 피복경질합금 소재에 관한 것이다.
본 발명은, 물리증착법의 단점인 기재와 비복박막간의 밀착성 저하와 고온화학증착법의 단점인 과도한 기재의 인성저하등을 해소하고 기재의 인성을 그대로 유지할 수 있도록 하기위하여 초경합금이나 질소함유 서메트로 된 기재의 표면에 600∼850℃의 저온화학증착법에 의하여 TiCN, TiC, TiCN 및 Al2O3중 선택된 1종 또는 2종 이상의 피복을 형성하는 것을 특징으로 하는 표면 피복경질합금 소재를 제공한다.
