In response to the surface defects of piston rod made of non-quenched and tempered steel after electroplating,through macroscopic,metallographic,scanning electron microscopy and other analysis,it is found that the surface defects are the iron chips in the grinding process that were not removed by ultrasonic alkali washing,and the coating peeling defect formed during the polishing process due to poor adhesion with the substrate after electroplating.Strengthening surface clean-ing and inspection before electroplating,the piston rod can effectively reduce the peeling defects on the surface coating of the piston rod by cleaning and removing the oxide skin and adhered foreign objects on the surface.
