摘要:
利用直线式离子注入机对抛光后的Cr4Mo4V轴承材料进行变能量的金属元素（Ti、Zr、Cr、Mo、Ta）注入，通过摩擦磨损测试机测试注入前后Cr4Mo4V的耐磨损性能，利用纳米压痕硬度仪、俄歇电子能谱（AES）和X射线光电子能谱（XPS）等检测表征手段，研究不同金属元素注入对Cr4Mo4V耐磨损性能的影响机制。结果表明：以测试条件下维持低摩擦因数0.2~0.3的运行时间看，Ti注入样品耐摩擦磨损性能提升约14倍，Zr注入试样的耐摩擦磨损性能提升超过20倍，ⅣB族Ti、Zr两种元素注入的Cr4Mo4V表现出较高的抗摩擦磨损性能；注入Zr对基材纳米硬度提升20%左右，而具有最佳的抗摩擦磨损性能；不同于其它的注入金属元素，Ti、Zr注入元素在基材内的浓度—深度分布中伴随出现了C、O的浓度峰分布，且Zr注入样品中C浓度峰最强、分布深度最广。

Abstract:
Polished Cr4Mo4V materials are implanted by different metallic elements, (such as titanium, zirconium, chromium, molybdenum and thallium), with alternated energy. The tribological properties of implanted/nonimplanted Cr4Mo4V are tested, and the mechanisms of friction and wear are further studied using nanohardness, auger electronic spectrometer (AES), and Xray photoelectron spectroscopy (XPS) techniques. The results show that antifriction and wear resistance of titanium implanted sample is improved 14 times, and over 20 times with zirconium implanted under the same test conditions, evaluated by duration of lower friction coefficient 0.20.3. Samples implanted by titanium/zirconium (belonging to ⅣB) perform high friction and wear resistance, especially the nanohardness of zirconium implanted sample are improved from 910 GPa to 12 GPa, obviously upgraded about 20%. Unlike other implanted metal elements, concentration peaks of carbon/oxygen exist, respectively, and distribute along with titanium/zirconium concentration and distance, and also zirconnium implanted sample has the widest concentration of carbon.
