γ'相是一种固溶体(Fe4最简单的微信赚钱方法 N),是在渗氮过程中,当α相处于氮的过饱和状态时发生的转变产物,硬度大于550HV。γ'相脆性不大。

ε相是近于Fe3 N和Fe2 N之间的一种固溶体,有的称为Fe2~3最简单的微信赚钱方法 N。ε相是在渗氮时,当γ'相达到氮的过饱和状态时形成的。ε相脆性稍大,硬度约为260HV。

ξ相是Fe2 N固溶体,其含氮量比ε相更高,脆性更大。在显微镜下不易与ε相区分,所以,也有将其归于ε相的。

在不锈钢渗氮组织中,除Fe4 N、Fe3 N、Fe2最简单的微信赚钱方法 N外,还存在合金氮化物。

氨的分解率对渗氮层的硬度及性质有明显的影响。氨的分解率与温度、压力、氨气输入速度等条件有关,太高的分解率,不能被工件吸收的分解物会以N2和H2形式存在,有碍于渗氮效果,随着氨分解率的降低,工件吸收的氮量逐渐增加到最大值,直至氨分解率降低到5%~10%时,分解物氮原子已满足不了工件吸收,工件吸收的氮量呈下降趋势,渗氮硬度降低,也达不到好的渗氮效果。所以,在实际的渗氮温度、压力条件下,氨的分解率一般控制在15%~45%。不锈钢中合金元素含量高,阻碍氮的吸收和扩散,所以,不锈钢渗氮时的温度应偏高,氨的分解率也相应提高。

离子渗氮就是将工件放在可形成真空的炉内,并通入含氮的气体介质(一般通入氨气),以工件为阴极,以炉壁为阳极(或另加辅助阳极),在阴-阳极之间加入高压直流电源,在电场的作用下,氨气被电离成氮、氢正离子,并快速冲向阴极(工件)在离子的轰击下,工件被加热到一定温度。同时,氮离子从阴极夺取电子还原为氮原子,氮原子与工件表面被轰击出的铁原子结合,形成FeN沉积在工件表面上,在离子轰击和热激活作用下分解成Fe、Fe2 N(ξ相)、Fe3 N(ε相)、Fe4 N(γ'相)。随着时间的延长,氮原子自工件表面向内扩散,完成离子渗氮过程。离子渗氮过程中,工件表面的反应原理见图7-2,2Cr13不锈钢离子渗氮层见图7-3,0Cr18Ni9不锈钢与45钢离子渗氮效果对比见图7-4。

(3)渗层表面硬度高。因为不锈钢有较高含量的铬、钼等合金元素,与一般碳钢和合金钢相比,渗氮层组织中除Fe4 N、Fe3 N外,还含有极高硬度的合金氮化物,所以,使得渗氮层表面硬度高于一般碳钢和一般合金钢渗氮层的硬度。见图7-4。

(4)不锈钢渗氮后对耐腐蚀性的影响。不锈钢渗氮后,因为一部分铬与氮结合,形成Cr2 N、CrN等铬的氮化物,降低了钢中的固溶含铬量,当然对耐腐蚀性有不利影响。
