Abstract

이 발명은 알루미늄재 엔진 블록의 실린더 보어 내벽에 기존의 주철재 실린더 라이너를 대신하는 코팅피막층이 코팅되도록 함으로서 엔진의 경량화와 열부하 감소 및 콤패트화, 그리고 성능 향상을 도모하도록 발명된 엔진 블록의 실린더보어 코팅 제조방법과 구조에 관한 것으로서, 용사법에 의해 메탈 또는 세라믹 및 그 그들의 혼합물로 이루어지는 코팅분말이 플라즈마 또는 아아크를 열원으로 하여 실린더 보어 내부에서 회전되면서 수직 이동되는 건에 의해 분사되는 코팅이 이루어지도록 하는 한편 실린더 보어 내벽에 기존의 실린더 라이너를 대신하는 코팅피막층이 형성되는 엔진블록을 얻을 수 있도록 된것이다.The present invention is a cylinder of the engine block invented to reduce the weight of the engine, reduce heat load and compact, and improve the performance by coating a coating film layer on the inner wall of the cylinder bore of the aluminum engine block in place of the existing cast iron cylinder liner The method and structure of the bore coating, the coating powder made of metal or ceramic and mixtures thereof by the thermal spraying method is to be sprayed by a gun that is moved vertically while rotating inside the cylinder bore by using a plasma or arc as a heat source On the other hand, it is possible to obtain an engine block in which a coating film layer is formed on the inner wall of the cylinder bore instead of the existing cylinder liner.
