Replacement of parts with complex shape and thin walls can be costly. In some cases the parts can be refurbished by using thermal spray coating processes to deposit a proper coating on the worn areas to restore dimensions without affecting the functionality and original geometry of the part. Often the surface restored by thermal spray offers better performance in service due to the specifics of the coating microstructure. We will investigate the development of coating techniques for restoration of a number of common parts from the Aeropol Aviation Services Corporation inventory. In particular we are going to select a proper coating material and deposition method for a valve body made out of aluminum alloy, and test the performance of the restored parts.

更换具有复杂形状和薄壁的部件可能是昂贵的。在某些情况下，可以通过使用热喷涂工艺在磨损区域上存款适当的涂层来翻新部件，以恢复尺寸，而不影响部件的功能和原始几何形状。由于涂层微观结构的特殊性，通过热喷涂修复的表面通常在使用中提供更好的性能。我们将研究涂层技术的发展，从Aeropol航空服务公司的库存恢复一些共同的部分。特别是针对铝合金阀体，选择合适的涂层材料和沉积方法，并对修复后的零件进行性能测试。
