实验研究了等离子体浸没离子注入沉积（pii & d）碳化钛（TiC）膜对AISI52100轴承钢表面涂层滚动接触疲劳（RCF）寿命的影响。测试包括平面光学显微镜（OM）、x射线衍射（XRD）、摩擦磨损行为、滚动接触疲劳寿命和纳米压痕测量。XRD谱图表明，薄膜中形成碳化钛相，处理后样品的显微硬度高于基体。采用常规光学显微镜观察滚动接触疲劳破坏轨迹。存在表面磨损和胶粘剂分层现象。结果表明，在5.1 GPa和90%置信度的赫兹应力水平下，处理后试样的最大RCF寿命分别延长了6.5倍。与基体相比，处理后试样的最大显微硬度提高了28.4%。在相同磨损条件下，摩擦系数从0.95下降到0.15。这种显著的疲劳性能似乎是由于显微组织、附着力、硬度和表面形貌的改善。因此，pii&d被认为是提高轴承RCF寿命的有前途的技术之一。
The effect of plasma immersion ion implantation and deposition (PIII&D) titanium carbide (TiC) film on the rolling contact fatigue (RCF) life of coated on AISI52100 bearing steel surface is studied experimentally. Testing include plan-view optical microscopy (OM), X-ray diffraction (XRD), friction and wear behaviors, rolling contact fatigue life and nano-indentation measurements. XRD patterns show that titanium carbide phase is formed in the film, and the microhardness of treated samples is higher than that of substrate. Rolling contact fatigue failure tracks were observed using conventional light microscope. Surface wear and adhesive delamination existed. Results indicate that the maximum RCF life of the treated sample prolong by 6.5 times at a Hertzian stress level of 5.1 GPa and 90% confidence level, respectively. Comparison with the substrate, the maximum microhardness of treated specimen is increased by 28.4%. The friction coefficient decreased from 0.95 to 0.15 under identical wear conditions. This remarkable fatigue performance appears to be due to a combination of improved microstructure, adhesion, hardness and surface topography. Therefore, the PIII&D is regarded as one of the promising technologies for improving the RCF life of bearing.
