中文摘要:
      目的 在去离子水环境中,研究GNiCr40Al3Ti合金表面制备的铬掺杂类金刚石(Cr-DLC)、氮化铬铝(CrAlN)和氮化铬(CrN)等薄膜的摩擦磨损性能。方法 在GNiCr40Al3Ti合金表面采用离子源辅助非平衡磁控溅射制备Cr-DLC薄膜,采用多弧离子镀技术制备CrAlN薄膜和CrN薄膜。利用冷场发射扫描电镜、拉曼光谱仪和X射线衍射仪,对薄膜的微观结构和形貌进行分析。利用显微硬度计、摩擦磨损试验机、白光干涉扫描轮廓仪等,对薄膜的硬度、摩擦磨损性能、磨痕二维轮廓等进行研究。结果 在10 h连续的去离子水环境摩擦过程中,CrN薄膜的平均摩擦系数最低,仅为0.17,比GNiCr40Al3Ti合金的摩擦系数降低了54%。与GNiCr40Al3Ti合金相比,其表面制备的Cr-DLC、CrAlN和CrN薄膜在去离子水环境摩擦条件下都减小了磨损体积,其中,CrN薄膜表现出最好的耐磨性,磨损体积为0.017 mm3,仅为GNiCr40Al3Ti合金磨损体积的0.18%。Cr-DLC薄膜与CrAlN薄膜的耐磨性不及CrN薄膜,主要是由薄膜的微观结构造成的,Cr-DLC薄膜的柱状疏松结构造成薄膜过早的被磨穿,CrAlN薄膜中存在的Cr相引起薄膜硬度降低,从而降低了抗剪切的能力。结论 在去离子水环境中,CrN薄膜具有最低的摩擦系数和最佳的耐磨性。
英文摘要:
      The work aims to study friction and wear properties of chromium doped diamond-like carbon (Cr-DLC) films, chromium aluminum nitride (CrAlN) films and chromium nitride (CrN) films prepared on the surface of GNiCr40Al3Ti alloy in deionized water environment. Cr-DLC films were prepared on GNiCr40Al3Ti alloy in the method of ion source assisted unbalanced magnetron sputtering. CrAlN films and CrN films were prepared by multi-arc ion plating technique. The microstructure and morphology of films were analyzed by scanning electron microscope, Raman spectrometer and X-ray diffractometer. The hardness, friction and wear properties and two-dimensional profile curves of wear scar of the films were tested by microhardness tester, tribo-tester as well as white light interference scanning profiler. In the 10 h continuous friction process of deionized water environment, the CrN films had the lowest average friction coefficient of only 0.17, which was 54% lower than that of the GNiCr40Al3Ti alloy. Compared with GNiCr40Al3Ti alloy, Cr-DLC films, CrAlN films and CrN films reduced wear volume under deionized water environment. The CrN films exhibited the best wear resistance with wear volume of 0.017 mm3, which was only 0.18% of the wear volume of the GNiCr40Al3Ti alloy. The wear resistance of Cr-DLC films and CrAlN films were not as good as that of CrN films, which was mainly caused by the microstructure of the films. The columnar loose structure of the Cr-DLC film caused the film to be worn through prematurely, and the Cr phase in the CrAlN film caused the hardness of the film to decrease, thereby reducing the ability to resist shear. CrN films have the lowest friction coefficient and the best wear resistance in deionized water environment.
