Passivation polishing is a commonly used process when machining and treating copper and its alloy parts, as it improves the surface finish of the workpiece while enhancing corrosion resistance. However, one of the main challenges often faced in this process is how to achieve a good polish without over-corroding the workpiece. In order to address this issue, this article will look at how to avoid excessive corrosion of copper parts when using passivation polishes in conjunction with Bigely specific product, copper passivation polishing agent BC-80.
In the aluminum alloy plating process, secondary zinc deposition is an important step. This process not only concerns the quality of the coating, but also directly affects the service life of the product. In this article, we will analyze the necessity of secondary zinc deposition in aluminum alloy plating, and understand which kind of zinc deposition water is beneficial to aluminum plating.
In the electroplating process, nickel removal is a crucial part, especially when reworking or repairing defective plating is required. How to use the nickel removal solution without corroding the iron substrate or causing it to change color is a challenge faced by many plating manufacturers and engineers.
Chemical degreasing powders are multi-component chemicals that typically contain sodium hydroxide, surfactants and other additives. Temperature affects the activity of these components and therefore the efficiency of degreasing. Generally, higher temperatures accelerate the rate of chemical reaction and improve the effectiveness of degreasing. However, high temperatures may cause the chemicals to decompose or cause corrosion on metal surfaces. Therefore, temperature control during degreasing needs to follow an optimized strategy that ensures rapid degreasing while avoiding overreaction and material damage.
In recent years, with the rapid development of new energy vehicles, electroplating technology plays a key role in ensuring the performance of auto parts and reducing manufacturing costs. Zinc-nickel alloy plating process has become a popular choice in the new energy vehicle industry due to its good corrosion resistance and mechanical strength. Among them, Bigely alkaline zinc-nickel alloy brightener BZ-617 has attracted much attention because of its own properties.
In the electroplating industry, alkaline galvanizing brighteners are widely used, and they can effectively improve the gloss and overall appearance quality of the plated layer. However, the presence of excessive iron impurities in the plating solution can have a significant impact on the plating process. In this article, we will discuss in detail the effects of excessive iron impurities in the plating bath when using alkaline galvanizing brighteners and mention why using Bigely alkaline galvanizing brightener, BZ-518, is a wise choice.
