Abstract

본 발명은 도금처리대책용 강부품의 제조방법에 관한 것으로, 질화성가스에 산화성가스를 첨가한 질화-산화가스분위기에서 강부품을 동시열처리하여 표면에 산화물층, 산소가 함유된 ε-질화물층을 형성하도록 한 것이다.The present invention relates to a method for manufacturing a steel component for the treatment of plating treatment, an ε-nitride layer containing an oxide layer and oxygen on the surface by simultaneously heat-treating the steel component in a nitride-oxidation gas atmosphere in which an oxidizing gas is added to the nitriding gas. To form.

본 발명은, 가스를 사용하기 때문에 염욕법과 관계된 공해문제를 일소하고 또한 종래의 가스법에 비해 질화처리후의 부가적이고 인위적인 산화열처리가 불필요하여 에너지절감, 작업공정의 단순화 및 피로강도가 큰 강부품의 제조에 잇점이 있다.The present invention eliminates the pollution problem associated with the salt bath method because of the use of gas, and does not require additional and artificial oxidative heat treatment after nitriding, compared to the conventional gas method, thereby reducing energy, simplifying work processes, and increasing fatigue strength. There is an advantage in manufacturing.
