熱處理工藝: 真空淬火，真空滲碳淬火，真空滲氮淬火
Heat Treatment: Vacuum Quenching, Vacuum Carburizing Quenching, Vacuum Nitrogen Infusion & Oil Quench.

真空滲氮淬火優(yōu)點(diǎn): 
其變形量僅是碳氮共滲淬火大約一半，同時(shí)，也只比氣體軟氮化的變形量稍微大一點(diǎn)而已。
Advantages for Using Nitrogen Infusion & Oil Quench: 
Little distortion (merely reaches the same degree as gas nitriding) and ? comparing to the product that went through carbonitriding.

真空滲碳淬火優(yōu)點(diǎn):
無結(jié)晶粒間的氧化，成品外觀良好，亦可以對(duì)細(xì)孔內(nèi)達(dá)成高濃度及均勻度的滲碳。
Advantages for Using Vacuum Carburizing Quenching:
No oxidization of the surface, also could achieve the carburizing in narrow holes with high concentration and distribution of the carburization.
