| Abstract: | A chromium-free passivating technology for zinc plating was developed, and the effects of passivating solution and process conditions on the passivation film were studied. Results showed that the passivation film reached (GB) grade 5 after 24 hours white rust resistance test and 72 hours neutral salt spraying test. |
