Claims (6)
- 중량으로 88%의 텅그스텐 카바이드, 12%의 닉켈과 0.01%의 바나디움 카바이드로 구성되였고, 1마이크론 이하의 최대 입자크기를 가지며 합성 윤활유에 대한 우수한 내부식성이 있음을 특징으로 하는 열처리에 의하여 소결된 침투형의 단단한 카바이드 기소(機素).
- 기소가 두 조각으로 된 접합선이 없는 깡통을 만드는데 사용하기 위한 동(銅) 공구인 청구범위 1에 따른 침투형의 단단한 카바이드 기소.
- 상기 기소의 열처리는 텅그스텐 카바이드, 닉켈 및 바나디움 카바이드 분말로된 주과를 탈탄기권내에서 700℃의 온도하에 약 2시간 예비 소결한 다음 약 1450℃의 온도까지 연속적으로 증가하는 온도에서 소결시킴으로 구성된 청구범위 1이나 2에 따른 침투형의 단단한 카바이드 기소.
- 상기 소결은 수소를 15″Hg의 분압으로 채워진 로내에서 600℃로 가열한 다음 로를 진공으로 하고 온도를 1300℃로 올린후 로를 15″Hg프로판의 분압으로 만든 다음 이 상태를 30분간 지속시킨 후 로를 진공으로 하여 다시 온도를 1450℃로 1시간 동안 증가시키는 것으로 구성된 청구범위 3에 따른 침투형의 단단한 카바이드 기소.
- 예비 소결된 주괴를 기소의 크기 및 형태로 제작함을 포함하는 청구범위 4에 따른 침투형의 단단한 카바이드 기소.
- 기소가 텅그스텐 카바이드 닉켈 및 바나듐 카바이드로부터의 주괴를 기압적으로 가압 성형한 주괴를 탄탈기권내에서 700℃의 온도하에 예비 소결시키고 예비 소결된 주괴를 기소의 크기 및 형태로 제작한 다음 1450℃까지 연속으로 증가하는 온도하에서 소결하는 청구범위 1이나 2에 따른 침투형의 카바이드 기소.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
