To use which process should depend on the thread requirements.
Surface hardening process refers to make surface hardening of investment castings,but the core still have strong toughness.Through this process,we can improve the wear resistance and fatigue resistance of investment castings.As the core still has good toughness and strength,so investment castings after case hardening have good resistance to impact load.Surface hardening treatment methods mainly include carburizing&quenching, nitriding, hard anodic oxidation, chrome plated, and metallic cementation, etc.
