Two technology including nitrocarburizing process and salt nitrocarburzing process haver been adopted. Several conclusions were obtained: firstly, nitrided layers consist of two layers including the outer white layer, mainly ε and γ′ with favorite errosion resistance, the inner dark layer consist of α-Fe.

再往里为扩散层，扩散层与原始组织无明显区别，是过饱和含氮的α-Fe固溶体，比原始组织更易受腐蚀；(2)试样经长时间氮碳共渗后，渗层最表面会出现疏松，这是因为Fe原子向外扩散，在ε相内造成Fe原子空位，空位向内扩散，并可能在晶界上或某些晶体缺陷处堆积，以致造成空洞。
