铝活塞是发动机的关键零件,其性能的好坏直接影响发动机的性能。其表面质量及锈蚀除影响活塞的几何尺寸和外观质量外,也影响结构强度,因此对活塞的内外质量提出了越来越高的要求。在生产中,发现毛坯、在制品及一些成品有锈蚀现象,严重的甚至产生批量废品,造成较大损失。解... Aluminum piston is a key part of the engine, the performance of a direct impact on the performance of the engine. Its surface quality and rust in addition to affecting the geometry and appearance of the piston quality, but also affect the structural strength, so the quality of the piston inside and outside the proposed higher and higher requirements. In production, found rough, in the finished products and some products have rust phenomenon, serious or even batch waste, resulting in greater loss. solution...
