The problem of fatigue in cold spray application

主講人 : Mario Guagliano

冷噴涂作為一種新型表面強(qiáng)化技術(shù)，除了作為防護(hù)涂層還可用于表面功能化及幾何修復(fù)，在增材制造領(lǐng)域具有廣泛的應(yīng)用前景。 本講座針對冷噴涂工藝對零件疲勞性能的影響研究進(jìn)行了綜述，并講述了主講人團(tuán)隊(duì)在冷噴涂方面的研究進(jìn)展，最后對冷噴涂工藝在零件疲勞強(qiáng)化中的應(yīng)用前景進(jìn)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.
