摘要

摘要冷喷涂涂层的粘合强度需要评估多个缺陷和性能分布。已经提出了两种方法来确定冷喷涂基底的粘合强度。界面剪切强度方法将碎裂试验与改进的威布尔模型相结合。碎片测试可以检查冷喷涂试样的几何（粗糙度）和性能（强度）变化的材料。该结果使我们深入了解了局部强度和涂层强度分布。断裂韧性方法使用电四点探针来识别裂纹萌生并计算涂层的能量释放率。74和120μm之间的Sn涂层显示出25和53之间的界面剪切强度 MPa，能量释放率在15和32 J m–2之间。测得的界面剪切强度与涂层厚度无关，而能量释放率取决于涂层厚度。

Adhesion of rough cold sprayed metal coatings on polymers

ABSTRACT The adhesion strength from the cold-spray coating requires assessing multiple flaws and property distributions. Two approaches have been proposed for determining the adhesion strength of the cold spray-coated substrate. The interfacial shear strength approach combines the fragmentation test with a modified Weibull model. Fragmentation testing can examine materials with geometrical (roughness) and property (strength) variations for cold spray-coated specimens. The results give an insight into local strength and the coating strength distribution. The fracture toughness approach uses an electrical four-point probe to identify crack initiation and calculate the energy release rate of the coating. Sn coatings between 74 and 120 μm show an interfacial shear strength between 25 and 53 MPa and an energy release rate between 15 and 32 J m–2. The measured interfacial shear strength was independent of the coating thickness, while the energy release rate depends on the coating thickness.
