Abstract

본 발명은 오스테나이트계 금속에 대하여 침탄처리를 하여 그 표면을 경질화하는 침탄처리방법에 관한 것으로서, 오스테나이트계 금속에 대해서 불화 처리한 후, 680℃이하의 저온에서 침탄처리하고, 이와 같이 불화처리함으로써 침탄시의 온도를 낮게 설정할 수 있게 되는 것을 특징으로 하며, 그 결과 오스테나이트계 금속내의 크롬성분이 탄화물이 되어서 석출되는 것이 방지되므로 오스테나이트계 금속내에 남는 크롬성분이 많아지기 때문에, 침탄에 의해 오스테나이트계 금속의 표면을 경질화할 수 있음과 동시에 높은 내식성도 유지할 수 있게 된다.
