With the wide application of coating materials in aerospace and other fields, their safety under fatigue conditions in service is important. However, research on the fatigue properties of ceramic hard coatings started late, and a unified standard is yet to be established to evaluate the fatigue life of hard coating-ductile substrate systems. Studies also present different opinions on whether coatings can improve or reduce the fatigue life of substrates. In this paper, the influence of the properties of ceramic coatings on fatigue performance is reviewed, and the effects of coating on the mechanism of fatigue crack initiation in substrates are discussed, aiming to help readers understand the fatigue behavior of hard coating-ductile substrate systems.

随着涂料在航空航天和其他领域的广泛应用，在疲劳条件下使用它们的安全性很重要。然而，对陶瓷硬质涂层的疲劳性能的研究起步较晚，并且尚未建立统一的标准来评估硬质涂层-延性基体系统的疲劳寿命。对于涂层是否可以改善或减少基材的疲劳寿命，研究也提出了不同的意见。本文综述了陶瓷涂层的性能对疲劳性能的影响，并讨论了涂层对基体疲劳裂纹萌生机理的影响，旨在帮助读者理解硬质涂层-韧性基体系统的疲劳行为。 。
