  • Many customers prefer the color appearance of hexavalent chromium passivation, and the use of trivalent chromium color zinc passivator, the color appearance of the workpiece does not meet the requirements, or the corrosion resistance of the workpiece coating is poor and affects the performance of the workpiece. Today, we introduce a trivalent chromium color zinc passivator BZ-207 with hexavalent chromium passivation appearance and high corrosion resistance.

  • The trivalent chromium black zinc passivation process has become a popular choice for galvanizing treatments in recent years due to its environmental credentials and low toxicity. However, despite its good corrosion resistance, it performs relatively poorly in terms of wear resistance. The causes of this phenomenon are mainly related to the physical properties, chemical structure and process control of the passivation film.

  • 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.

  • 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:
