Abstract

본 발명은 다이아몬드 등의 초경질막과 초경합금기재가 강고하게 부착한 초경질막 피복부재와 그 제조방법을 제공하는 것이다.
본 발명은 초경합금기재를 열처리하여 기재표면상에 기재표면부에 가까운 기재중의 결합금속을 반구상으로 석출시킨다. 이 석출물을 그대로 남기던지 또는 그 일부 혹은 전부를 제거하고, 이 표면상에 화학적기상 합성법에 의하여 다이아몬드 및/또는 다이아몬드 모양 탄소를 생성하는 것을 특징으로 하는 것이다.
이 석출물의 생성에 의하여 초경질막과 초경합금기재의 부착력은 현저하게 강하게 되고, 두꺼운 막의 형성이 가능하게 된다.
