Abstract
소정의 온도 범위에서 고온 개스에 의해 침해되고 연소 플랜트, 열 교환기 또는 비슷한 장치에서 금속과 소정의 기초 재료로서 만들어지고 플라즈마 제트기술에 의해 금속, 탄화물, 산화물 세라믹 또는 실리사이드 재료 또는 그것들의 혼합물의 분말이 도포되는 벽면에 보호막을 형성시키는 공정이다. 본발명은 다음과 같이 제안한다. a)벽 표면이 거칠게 되며, b)벽면의 기초 재료가 활성화 되며, c)그 즉시, 분위기 조건하에서 상온에서 플라즈마 분사 기술에 의해 분말이 도포되며, d)분말의 조성이 사전에 선택되어,무응력(상온)의 상태에서 온도의 함수로서 응력이 기초 재료와 시험재의 열팽창 계수로 밝혀지며 기초 재료와 여러가지 분말로 부터 생성된 도포된 코팅 사이의 전환 지역이 50∼800N/㎟ 바람직하게 500∼800N/㎟의 인장응력을 주며, 소정의 온도 범위에서 제로 토는 약간의 압축응력을 보여준다.
