摘要
对35钢进行QPQ盐浴氮化复合处理,运用X射线衍射(XRD)和金相显微镜(OM)对处理后的样品进行相结构和组织形貌分析,另外还对处理前、后的35钢分别进行了显微硬度测试、极化曲线测试以及滑动磨损性能实验。结果表明:经过QPQ处理后的35钢表面生成了一层铁的氮化物和氧化物,其相应的耐磨性能和耐腐蚀性能都有了很大提高。
The QPQ （Quench-Polish-Quench） complex salt bath treatment of 35 steel was carried out, the phase and microstructure were analyzed by X-ray and OM respectively, meanwhile, the microhardness, polarization curves and slide wear resistance of 35 steel before and after QPQ treatment were also tested. The results show that Fe2-3N and Fe304 are formed on the surface of the sample, which contributes to high slide wear and corrosion resistance of the 35 steel after QPQ complex salt bath treatment.
