There are many reasons why low chromium white passivation tends to appear color, and the common ones are related to the four aspects of the operation process.
(1) It is related to the imbalance of the process recipe in the passivation solution. The concentration of the white passivation solution is relatively low. When one of the components is consumed slightly faster, the proportion between the components will be out of balance, which will affect the quality of the film。
The corrosion protection of uranium and uranium alloys has a problem of poor coating tightness, which is mainly due to the adsorption of hydrogen molecules on the cathode side reaction in the plating process. In order to further improve the compactness of the plating layer and improve the physical and chemical properties of the plating layer, pulse plating can be used to obtain a plating layer with finer crystallinity, lower internal stress in the plating layer, and lower hydrogen content. In addition, cyanide-free galvanizing should be used to eliminate the hazard of cyanide
