In the electroplating industry, the appearance and corrosion resistance of galvanized black passivated products have always been the focus of manufacturers' attention. Many manufacturers often encounter the problem that the appearance of galvanized black passivate is not black enough and the salt spray performance is not up to standard during the production process of using trivalent chromium black zinc passivate. In order to help electroplating manufacturers to solve this problem, we have summarized a three-step solution through our service cases over the years.
Step 1, make sure the oil and rust removal is clean and thorough, and the blind holes in the crevices should be cleaned in place. This is because a clean surface is the basis for a good coating and passivation film, and any residual oil or rust will affect the formation and performance of the coating and passivation film. By using our degreasing and descaling products, we can ensure that the surface of the galvanized layer is clean and flawless, laying a solid foundation for the subsequent electro-galvanizing passivation process.
Step 2, Bigely Technology also controls the quality of the zinc coating. We know that the quality of the zinc coating is critical to the performance of the passivate film, so we start with the temperature, the zinc brightener and other aspects to ensure that the quality of the zinc layer is stable and reliable. Only in this way can a uniform and dense passivation film be formed in the subsequent production with trivalent chromium black zinc passivator, thus enhancing the corrosion resistance of the product.
Step 3, passivation process As a key step to enhance the appearance and corrosion resistance of galvanized black passivated products, Bigely Technology has put a lot of effort into it. Our trivalent chromium black zinc passivator is able to form a black, bright and corrosion resistant passivation film during the passivation process. This passivation film not only has good corrosion resistance, but also significantly improves the appearance of the product, making it more aesthetically pleasing.
