| Research Abstract |
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.
