    摘要:

    本文研究了陰極電弧離子滲鈦對(duì)316L不銹鋼結(jié)構(gòu)及摩擦學(xué)性能的影響。結(jié)果表明：利用陰極電弧離子滲金屬技術(shù)在316L不銹鋼表面制備的滲鈦層峰值鈦含量為66 wt.%，滲鈦層主要由Fe2Ti和NiTi相組成，滲層與基體結(jié)合牢固；表面硬度由基體的200 HV提高到了400HV，硬化層深度約為150 μm；在干摩擦條件下，滲鈦的不銹鋼樣品摩擦系數(shù)明顯低于未滲鈦樣品，磨損率降低到未滲鈦樣品的1/7。未滲鈦樣品的磨損機(jī)制為磨料磨損、氧化磨損和粘著磨損，滲鈦樣品的磨損主要是滲層局部剝落引起的。

    Abstract:

    The influence of cathodic arc plasma titanizing on the structure and tribological performance of 316L stainless steels was studied by scanning electron microscope, X-ray diffractometer, micro-hardness tester, 3D profile-meter, and reciprocating tribometer in the paper. It was found that the closely adherent titanized layer with a peak titanium content of 66 wt.% can be obtained by cathodic arc plasma titanizing. The titanized layer is composed of Fe2Ti and NiTi; the surface hardness of the titanized layer with a depth of 150μm is increased to 400 HV from 200 HV of original substrate. Under dry friction, the friction coefficient of the titanized layer is obviously lower than that of the original substrate, and the cathodic arc plasma titanizing improves the wear resistance of 316L stainless steels by 6 times. The wear mechanism of the original substrate is abrasive wear, oxidation wear and adhesive wear, while the wear mechanism of the titanized samples is mass loss caused by flaking of the particles in the titanized layer.
