Abstract

Abstract Rolling contact fatigue (RCF) of sprayed coating is complicated process relating to materials, structures, loading conditions, etc. Herein, the research works over the past decades in RCF of sprayed coatings are summarized here to provide a guidance to further explore the new research interests. Firstly, comprehensive summaries including the common RCF-resisted coating materials, the regular RCF setups, typical failure modes of sprayed coatings, and statistical characterization methods for RCF lifetime are illustrated. Secondly, the influence of surface integrity on RCF behavior of sprayed coating is discussed. The according mechanisms are also discussed by fracture analysis, numerical calculation, and finite element method (FEM). Thirdly, the influence of working condition on RCF behavior of sprayed coating is discussed. The shear stress is recognized as the major contribution of the RCF fracture, and the sliding during rolling contact will deteriorate the lifetime of sprayed coating. Additionally, some new techniques and methodologies have been reported in the investigations of RCF behaviors of sprayed coatings. Nondestructive testing (NDT) and signal processing methods are critical in the detection of micro-fractures within the sprayed coatings. Finally, we have proposed some suggests in future investigation of RCF of sprayed coating based on the previous research achievements.

热喷涂涂层滚动接触疲劳性能研究进展

摘要喷涂涂层的滚动接触疲劳是一个复杂的过程，涉及到材料、结构、载荷条件等方面。本文对近几十年来喷涂涂料RCF的研究工作进行了总结，为进一步探索新的研究方向提供指导。首先，对常见的抗RCF涂层材料、常规RCF设置、喷涂涂层的典型失效模式以及RCF寿命的统计表征方法进行了综述。其次，讨论了表面完整性对喷涂涂层RCF性能的影响。并通过断裂分析、数值计算和有限元分析等方法探讨了其机理。第三，讨论了工况对喷涂涂层RCF性能的影响。剪切应力是RCF断裂的主要原因，滚动接触时的滑动会降低涂层的使用寿命。此外，一些新的技术和方法也被报道用于研究喷涂涂层的RCF行为。无损检测(NDT)和信号处理方法是检测涂层微裂纹的关键。最后，在总结前人研究成果的基础上，对喷涂涂层RCF的进一步研究提出了建议。
