滚动接触疲劳性能是评价膜层性能的重要指标之一。影响零件滚动接触疲劳性能的因素主要分为膜层自身结构完整性和服役条件两大类。膜层自身结构完整性又受制于涂覆工艺、材料体系、后处理方式等因素。在服役工况确定的情况下，膜层自身结构完整性对零件的接触疲劳性能起决定性的作用。不同的涂覆工艺、材料体系、后处理方式对零件的滚动接触疲劳性能及失效机理的影响不尽相同。本文综述了涂覆工艺、材料体系、后处理方式对基体表面异质材料滚动接触疲劳性能与失效机理的影响，发现对滚动疲劳失效机理也存在作用。最后，总结了目前关于膜层滚动接触疲劳研究中存在的问题，探讨了解决问题的方法，以期为基体表面膜层的接触疲劳寿命预测奠定良好的基础。

ABSTRACT:The rolling contact fatigue performance is one of the important indexes of evaluating the membrane layer perform-ance. The factors affecting the rolling contact fatigue performance of parts are mainly divided into the structural integrity of the membrane layer itself and the service conditions. The structural integrity of the layer itself is subjected to the factors of diverse coat-ing process, material system and post-processing method, and so on. When the service condition is fixed, the structural integrity of the layer itself plays a decisive role in contact fatigue performance. Diverse coating process, material system and post-processing method have different influence on the rolling contact fatigue performance and failure mechanism of the parts. The influences of the coating process, material system and post-processing method on the rolling contact fatigue performance of heterogeneous material on the substrate surface were summarized in this paper. It could be found that the factors of coating process, material system, post-processing mode also had an effect on the rolling fatigue failure mechanisms. Finally, the existing problems of current research a-bout the rolling contact fatigue of membrane layer were summarized, as well as the solve methods, in order to build good foundation for predicting contact fatigue life of substrate surface membrane layer.
