What are some good methods to improve the adhesion of the electroplated coating on aluminum materials? The key lies in choosing the right chemical zinc immersion solution and paying attention to the operational details when using it.
In aluminum alloy electroplating, one of the key steps that determine the adhesion of the coating is chemical zinc immersion. When using Bigely chemical zinc immersion solution BC-22, the deposited zinc coating has two characteristics:
1. The coating is uniform, without pinholes, thin and dense
2. It has a small bite effect on aluminum alloys
The characteristics of these two zinc coatings determine that it has a good adhesion to aluminum alloy. We know that aluminum alloy electroplating requires electroless plating or electroplating on the basis of the zinc coating (sometimes both are used, but it still depends on the requirements of the electroplating factory customer for the order). If the foundation is well laid, then the adhesion of the subsequent electroplating will have a solid guarantee. It can produce a non-bubbling, uniform and smooth coating.
