The problem of fatigue in cold spray application

主讲人 : Mario Guagliano

冷喷涂作为一种新型表面强化技术，除了作为防护涂层还可用于表面功能化及几何修复，在增材制造领域具有广泛的应用前景。 本讲座针对冷喷涂工艺对零件疲劳性能的影响研究进行了综述，并讲述了主讲人团队在冷喷涂方面的研究进展，最后对冷喷涂工艺在零件疲劳强化中的应用前景进行了展望。

Cold spray technology has recently gained much attention for applications beyond its primary cause of protective coating deposition. It has found its way for depositing thin films for surface functionalization, thick coatings for geometrical restoration, and has exhibited a high potential for additive manufacturing. As cold spray paves its way towards more structural applications, evaluating its performance under cyclic loading is significantly importance. In the presentation, the current state of the art on the contribution of various forms of cold spray deposits to fatigue strength is reviewed and the results obtained by the research group of the speaker are critically discussed as well as future perspectives for the application of cold spray to structural parts subjected to fatigue loads.
