| Abstract: | The technology for golden-yellowish passivation of zinc coating was studied. The firststep of the passivation was carried out in a chromate solution, then a primary film was formed in the air. The second step was processed in a solution of potassium dichromate and sulfuric acid. Thereafter the final passivation film was obtained,which possessed golden-yellowish apparence and good quality against abrasion.In addition,the formation mechanism of passivation film,the adjustment and maintenance of passivation solution were also discussed. |
