    摘要:

    采用磁控濺射與低溫離子滲硫復(fù)合處理工藝原位合成了CrN/MoS2固體自潤(rùn)滑復(fù)合膜。采用X射線光電子能譜(XPS)、俄歇電子能譜儀(AES)和掃描電子顯微鏡(SEM)等分析方法對(duì)CrN基固體自潤(rùn)滑復(fù)合膜的顯微組織進(jìn)行分析。并通過CETR滑動(dòng)磨損試驗(yàn)機(jī)，對(duì)CrMoN復(fù)合膜及CrN/MoS2自潤(rùn)滑復(fù)合膜的摩擦學(xué)性能進(jìn)行了比較研究；通過SEM對(duì)磨痕形貌進(jìn)行了觀察。結(jié)果顯示，CrMoN復(fù)合膜經(jīng)滲硫處理后，主要合成了MoS2潤(rùn)滑相，滲硫?qū)雍穸燃s為500 nm，主要相結(jié)構(gòu)為CrN與MoS2及少量MoN。與CrMoN復(fù)合膜相比，CrN/MoS2固體自潤(rùn)滑復(fù)合膜摩擦系數(shù)較低、磨損體積較小，具有較好的耐磨性和減摩性。同時(shí)，對(duì)CrN/MoS2固體自潤(rùn)滑復(fù)合膜的成膜機(jī)理及磨損機(jī)制進(jìn)行了探討

    Abstract:

    The in-situ synthesis CrN/MoS2 solid self-lubricant composite coating was obtained by magnetron sputtering and low-temperature ion sulfuring. The XPS, AES and SEM equipped with EDS were used to observe and analyze the microstructure of the composite coating. The results show that the MoS2 is composed of sulfur which is infiltrated in 500 nm depth of the composite coating. The CETR inching tribology tester was used to analyze the tribological properties of CrN-based composite coating. The wear volume from big to small is CrMoN＞CrN/MoS2. It means that the CrN/MoS2 solid self-lubricant composite coating shows better wear resistance and antifriction. The film-forming mechanism and the frictional wear mechanism of CrN-based solid self-lubricant composite coating were discussed
