利用三球-棒试验机研究了AISI 52100轴承钢表面氮等离子体浸没离子注入（PIII）后的滚动接触疲劳性能和力学性能。测试研究包括光学显微镜（OM），摩擦和磨损行为，滚动接触疲劳寿命，和纳米压痕测量。结果表明，滚动体在表层或近表层失效。此外，在RCF测试之后，在滚动元件的表面上观察到可观量的表面磨损。处理后试样的最大显微硬度约为基体的2倍。处理后试样的摩擦系数从0.90降低到0.15。在Hertzian应力水平为5.1GPa和置信水平为90%时，处理后的L10寿命和L50寿命分别提高了99.6%和236.3%。OM形貌分析结果表明，表面粗糙度、工艺参数和内部缺陷在表面和近表面引发的RCF中起着重要作用。这种疲劳性能和力学性能的改善归因于在氮-PIII过程中形成氮化物相结构和残余压应力的组合。
Rolling contact fatigue (RCF) performance and mechanical characteristics of nitrogen plasma immersion ion implantation (PIII) on AISI52100 bearing steel surface has been investigated using a conventional three ball-on-rod rig. Testing investigations include optical microscopy (OM), friction and wear behavior, rolling contact fatigue life, and nano-indentation measurements. Results indicate that the rolling elements failed at the surface or near-surface layer. Moreover, an appreciable amount of surface wear was observed on the surface of the rolling elements after RCF tests. The maximum microhardness of treated samples is nearly twice as that of substrate. The friction coefficient of the treated samples is decreased from 0.90 to 0.15. The L10life of the treated specimens increase by 99.6% and L50life enhance by 236.3% at a Hertzian stress level of 5.1 GPa and 90% confidence level, respectively. OM morphology results indicate that the surface roughness, processing parameters, and inner defects play an important role in surface and near-surface initiated RCF. This improvement of fatigue and mechanical performance is attributed to form a combination of nitrides phase structure and residual compressive stress during the nitrogen-PIII process.
