Abstract

본 발명은 니켈계 초합금으로 형성된 제품, 특히 산업용 가스 터빈 엔진 노즐을 보수하기 위한 브레이징재를 개시한다. 브레이징재는 바람직하게는 분말 형태이고 분말과 함께 슬러리를 형성하는 결합제와 같은 적절한 용액에 분산된 니켈계 브레이징 합금으로 구성된다. 브레이징 합금은 산업용 가스 터빈 노즐의 고온 작동 환경에 견딜 수 있고 보수될 초합금의 재결정화 온도 미만의 융점을 갖도록 조성화된다. 브레이징 합금에 대한 바람직한 조성은, 중량%로, 약 14 내지 24의 크롬, 약 6 내지 15의 코발트, 약 0.7 내지 2.5의 붕소, 약 1.0 내지 2.0의 티타늄, 약 0.6내지 1.0의 알루미늄, 약 1.0 내지 1.4의 텅스텐, 약 0.4 내지 0.6의 콜롬븀, 약 0.5 내지 0.7의 탄탈륨, 약 0.7까지의 철, 및 잔부의 니켈과 불가피한 불순물로 이루어진다.
