激光涂层低应力多冲形变分析

Analysis of Laser Cladding Layer Distortion under Low Stress Repeated Impact

通过对带涂层试样的多冲试验,对不同冲击次数下涂层和基体的厚度变化进行对比,发现即使在低于材料屈服极限的冲击应力下,材料也会产生宏观塑性变形。针对实验条件及结果,对此现象产生的原因进行了分析。

Through the repeat impact test of coating workpieces and comparison between the changes of coating and base thickness under different impact times, it is finded that under impact stress even less than yield limit, material of workpieces appeared macroscopical plastic deformation. Aiming at the condition and result of the test, this article analyzes the cause of this phenomenon.
