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.

用复杂形状和薄壁的零件更换可能是昂贵的。在某些情况下，可以通过使用热喷雾涂层工艺对零件进行翻新，以将适当的涂层沉积在磨损区域，以恢复尺寸，而不会影响零件的功能和原始几何形状。通常，由于涂料微观结构的细节，通过热喷雾恢复的表面提供了更好的服务性能。我们将研究涂层技术的开发，以恢复Aeropol Aviation Services Corporation Contuctory的许多常见部分。特别是，我们将为铝合金制成的阀体选择适当的涂层材料和沉积方法，并测试已还原部分的性能。
