项目摘要
This work investigated dominant factor on mechanical properties of cold sprayed coating. Local area bonding, which is occurred in true contact area in particle interface is key mechanism of cold spray coating. True contact area bears material strength of cold sprayed coating. However, true contact bonding is weaker than ideal metallic bonding. Moreover, the density of cold spray coating is lower than that of bulk material. The density reduction is mainly occurred in true contact area. From these experimental evidences, the microstructure of true contact area is also important factor of mechanical property. Therefore, materials strength of cold spray is controlled by true contact area and interface structure of its.
这项工作研究了冷喷涂涂层的机械性能的主要因素。粒子界面中的真实接触区域中发生的局部粘结是冷喷涂涂料的关键机制。真正的接触区域带有冷喷涂涂层的物质强度。但是,真正的接触键比理想的金属粘合弱。此外,冷喷涂的密度低于散装材料的密度。密度降低主要发生在真正的接触区域。从这些实验证据中,真实接触面积的微观结构也是机械性能的重要因素。因此,冷喷雾的材料强度由真实接触区域及其界面结构控制。
