Surface modification of 45 steel was investigated by hot filament gas discharge and radio-frequency (RF) glow discharge nitrogen plasma immersion ion implantation (PIII) techniques. The chemical composition and microstructure of the modified layer were characterized by X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy(SEM), respectively. The microhardness, friction and wear behavior, corrosion resistance were also evaluated. The results reveal that the surface properties of 45 steel are enhanced by the two kinds of PIII,however,the RF glow discharge PIII produces the improvement of the surface properties more markedly. The microhardness increases by 76 8%, friction coefficient decreases to 0 3, and the corrosion resistance of the samples treated by RF glow discharge PIII is improved significantly.

采用灯丝放电和射频 (RF)辉光放电等离子体浸没离子注入 (PIII)工艺对 4 5钢表面进行了氮离子注入强化处理。通过X射线光电子能谱 (XPS)、扫描电子显微镜 (SEM)、显微硬度、针 -盘磨损和电化学腐蚀试验等测试手段 ,分析比较了经灯丝放电PIII和RF辉光放电PIII改性后试样表面元素的浓度分布、显微硬度、摩擦磨损性能和耐腐蚀性能。结果表明 :不同条件下的氮离子注入均能提高 4 5钢表面的显微硬度、耐磨性和抗腐蚀性能 ;且RF辉光放电PIII处理后试样的显微硬度提高了 76 8% ,摩擦系数下降到 0 3,与灯丝放电PIII处理后的试样相比 ,其表面强化效果更加明显。

The surface properties of Ti6Al4V alloy were investigated by plasma immersion ion implantation (PIII) technique. Modification effect of hot filament gas discharge PIII was compared with that of radio-frequency (RF) glow discharge PIII. The phase composition, and microstructure of samples were characterized by X-ray diffraction (XRD), and Scanning electron microscope (SEM).

The surface properties of Ti6Al4V alloy were investigated by plasma immersion ion implantation (PIII) technique. Modification effect of hot filament gas discharge PIII was compared with that of radio-frequency (RF) glow discharge PIII. The phase composition, and microstructure of samples were characterized by X-ray diffraction (XRD), and Scanning electron microscope (SEM). The microhardness, friction and wear behavior of treated- and untreated- coupons were also measured. The results reveal that the large crystal grains (α-β phase) are changed into small ones. The superhard TiN layer is formed on the surface. The microhardness is increased by 80 percent, friction coefficient is reduced to 0.16, and wear resistance is improved significantly.

研究了等离子体浸没离子注入(PIII)技术对Ti6Al4V合金表面性能的影响。分析比较了灯丝放电PIII和射频辉光放电PIII对基体表面进行氮离子注入后的改性效果。应用X射线衍射仪(XRD),扫描电镜(SEM)分析了注入层的相组成和组织结构;测试了经不同PIII工艺参数处理后试样的显微硬度和摩擦磨损性能。结果表明:氮离子注入使Ti6Al4V的粗大晶粒(α-β相)转变为细小致密的晶粒,表面层中形成了耐磨相TiN;处理后试样表面的显微硬度提高了80%,摩擦系数降到0.16,抗磨损性能得到了显著提高。
