  • Abstract Carburizing is widely used to improve steel wear and fatigue resistance. If some area of components are not required hardening by the carburizing, the copper plating was used to prohibit the carbon atom to diffuse into the steel. However, the diffusion between copper and iron couple was occurred, the effect of carburizing parameter on the microstructure and property of carburized component should be noted. The research focuses on the pretreatment effect of copper plating on the the microstructure and property of carburized component. The pretreatment includes copper plating. In addition, the failure of steel component by carburizing with pretreatment will also be evaluated by using impact tests. Microstructure analysis, microhardness and impact tests will be conducted. The results shows, SCM415 specimens with copper plating on surface held at carburizing temperature 960℃ for 2 hours. Copper plating layer and the substrate interface found a slightly diffusion of copper into the grain boundaries. As carburizing temperature and temperature holding time increased, more copper diffusion into grain boundaries. Case depth of unplated specimens increased with carburizing temperature and temperature holding time increased.
