摘要(Abstract)：

采用真空感应渗氮方法在20Cr Mn Ti钢表面制备渗氮层,利用X射线衍射仪、扫描电镜、显微硬度计和摩擦磨损试验机等分析了渗氮层的物相、组织结构、致密性、显微硬度梯度和耐磨性。结果表明:真空脉冲感应渗氮1 h就能够制备出较为致密的渗氮层,其硬度超过800 HV0.025,扩散层深度达到300μm;渗氮层主要由合金氮化物(Mn_4N,Cr_2N)和铁氮化合物(Fe_(4.4)N,Fe_3N,Fe_2N)组成,随着渗氮压力的增加,渗氮层由含氮量低的铁氮化合物逐渐转变为高氮的铁氮化合物;感应渗氮的气体压力对渗氮层的厚度影响不大,随着渗氮气体压力的增加,渗氮层的厚度有小幅度的增加,但是当渗氮气体压力过大时,渗氮层的脆性增大;当渗氮气体压力为-30 k Pa时,渗氮层的磨损率最低,大大提高了基体的耐磨性。
