The necessary choice of electroplating additives: zinc nickel alloy passivator
Nov 25,2023
Zinc-nickel alloy passivator is an indispensable additive in electroplating process. It can effectively improve the corrosion resistance of the plating layer and improve the quality and life of the product. This paper will introduce the importance of zinc-nickel alloy passivator, and discuss how to choose suitable passivator.
First, let us understand the role of zinc-nickel alloy passivator. During the electroplating process, the zinc-nickel alloy passivator can react with the metal ions in the electrolyte to form a dense passivation film. This film can block the erosion of oxygen, water and other harmful substances, thereby improving the corrosion resistance of the plating layer. The zinc-nickel alloy passivator can also enhance the hardness and adhesion of the plating layer, making it more wear-resistant and corrosion-resistant.
When selecting a zinc-nickel alloy passivator, it is first necessary to consider its chemical composition. A good quality passivator should have an appropriate zinc and nickel content to ensure the formation of a uniform and stable passivation film. In addition, attention should be paid to the amount of passivating agent and operating conditions to obtain a better passivation effect.
Secondly, the stability of the passivator is also an important factor in the selection. In the electroplating process, the passivator needs to have a long service life and be able to maintain stable performance. This can reduce the number of frequent replacement of passivation agent, improve production efficiency.
In addition, the environmental protection of the passivator is also one of the factors to be considered. Choosing a passivator that meets environmental protection standards will not only help reduce environmental pollution, but also improve the image and competitiveness of the company.
In the market, there are many different types of zinc-nickel alloy passivators to choose from. According to different electroplating requirements and product characteristics, you can choose a suitable passivation agent. In general, high quality passivators generally have a higher cost, but can provide better performance and stability.
To summarize, the selection of a suitable zinc-nickel alloy passivator is critical to the success of the electroplating process. Considering the chemical composition, stability and environmental protection, the selection of high quality passivator can improve the quality and corrosion resistance of the electroplated layer, and thus improve the market competitiveness of the product.
