Abstract: 본 발명은 열 차폐 코팅의 수명을 향상시키고자 금속 중간 결합층에 치밀하고 견고한 고온 내산화성이 높은 알루미늄 산화물층을 얻기 위한 열처리 공정에 관한 것이다.
본 발명에 의한 열처리 공정은 기존의 열 차폐 코팅 공정과 모두 동일하지만 단지 공정 중간단계에서 모재에 금속 중간결합층을 코팅한 후 예산화처리를 하는 것만 다르다.
예산화처리는 중간 결합층까지만 코팅한 시편을 대기 중에서 1050℃에서 최대 50시간까지 열처리를 통해 금속 중간결합 코팅층 위에 치밀하고 견고한 알루미늄 산화층을 얻는 것을 목적으로 한다.
상기 방법으로 처리된 열 차폐 코팅의 시편을 1100℃ 공기 중에서 반복산화 시험한 결과 아주 우수한 내산화 특성을 보였으며, 열충격 특성 또한 우수하였다.-
