Trivalent chromium blue and white passivation solution is widely used in the electroplating industry, mainly for passivation treatment after galvanizing process. Its main function is to improve the corrosion resistance of the plated layer. However, with the use of time, the passivation solution will gradually aging. The causes of aging include the accumulation of organic impurities, non-uniformity of the components in the passivation solution, changes in pH, solution temperature and contamination with metal ions. Changes in these factors directly affect the performance of the passivation solution, leading to a series of plating failures.
Zincate galvanizing brightener BZ-513 is the product of Bigely Technology, which integrates the advantages of domestic and foreign galvanizing technology and adopts the imported raw materials from Germany, which is suitable for cyanide-free alkaline zinc process, with simple process maintenance, good brightness and no brittleness of plating, and uniform thickness in high and low zones. Then, how to maintain BZ-513 when using?
When methanesulfonic acid tin plating additive is used, the acidity of the plating solution is relatively low, and the corrosion is relatively small. In the use of methylsulfonic acid tin plating additives, we can understand the advantages and disadvantages of additives through performance tests. The following takes the methylsulfonic acid tin plating additive Sn-819 from Bigely Technology as an example to conduct a performance test:
Matte tin plating is a widely used electroplating process used to deposit a uniform layer of tin on metal surfaces to provide corrosion protection, increase solderability and enhance appearance. This tin layer has a certain "matte" or "non-glossy" effect, as opposed to shiny tin plating, and is characterized by the following:
In the sulfate tin plating process, tetravalent tin is usually not directly involved in the formation of the plated layer, but it can occur due to oxidation of divalent tin in the plating solution. This oxidation can be triggered by several factors, including anodic reactions during the plating process, natural oxidation of the bath, and improper storage and handling.
The high-temperature nickel plating process is an industrial surface treatment technology that involves depositing a nickel coating on the surface of a metal or other material. The main purpose of this treatment technique is to improve the corrosion resistance, abrasion resistance, and high temperature resistance of the material, as well as to improve its surface finish. Below are a few important roles and application areas of the electroplated high temperature nickel process:
