The alkaline zinc-nickel alloy plating process is widely used in demanding environments such as automotive parts and the aerospace industry because of its excellent corrosion resistance and mechanical properties. However, despite the many advantages of this process, the problem of scorching of the plated layer occurs from time to time during the use of alkaline zinc-nickel alloy additives. In this article, we will analyze the causes and solutions of this phenomenon in detail.
First of all, the main causes of coating scorch are mostly focused on the composition of the plating solution, operating conditions and the use of additives. For example, too high current density can easily lead to localized overheating of the electrode, which in turn triggers the scorching phenomenon. In addition, too high or unstable concentration of nickel ions in the plating solution can also cause uneven surface of the plated layer or even scorching.
On the other hand, the selection and rational use of alkaline zinc-nickel alloy additives is one of the important factors to avoid burning of the plated layer. Additives can effectively stabilize the composition of the plating solution and make the deposition process more uniform, thus avoiding local overheating. In addition, reasonable additives can also improve the conductivity and dispersion ability of the plating solution, effectively preventing the occurrence of burning problems.
The use of Bigely alkaline zinc-nickel alloy additive BZ-617 enhances the quality of the coating. This zinc-nickel alloy additive is capable of achieving 16% nickel alloy content and provides good corrosion resistance appearance and tolerance to post-passivation heat treatments.
BZ-617 additive stabilizes the current distribution during the plating process, prevents excessive aggregation of metal ions on the electrode surface and avoids high temperature-induced scorching of the plated layer. At the same time, its stability and good dispersing ability ensure uniform deposition of the plated layer, greatly reducing the risk of localized overheating and scorching.
In summary, plating charring is a problem that needs special attention in alkaline zinc-nickel alloy plating process, which mainly includes high current density, unstable composition of plating solution and inappropriate use of additives. The selection of Bigely alkaline zinc-nickel alloy additive BZ-617 can effectively solve these problems, providing good corrosion resistance and beautiful appearance, so as to ensure the smooth progress of the plating process.
