| Abstract: | SEM is adopted to study the removing effect of bluing,ultrasonic acid pickling on the large springs.The influences of two different pretreatment techniques on adhesion and corrosion resistance of zinc electroplating films are also studied.The results show that bluing and ultrasonic acid pickling can remove the obstinate oxide scale on the surface of large springs and can improve the adhesion and corrosion resistance of zinc films on large springs. |

| Keywords: | bluing ultrasonic acid pickling adhesion corrosion resistance |
