We use high-sulfur nickel additives to obtain nickel coatings with a sulfur content of 0.12% to 0.25%.It is mainly used for the protection of steel and zinc alloy substrates and the intermediate layer of decorative coatings, which can effectively improve the corrosion resistance of coatings.So when we use high-sulfur nickel additives, how should the bath be maintained?
In the production process using the nickel sealing additives, the inclusion of non-conductive particles in the nickel-sealed coating can reduce the porosity of the coating.In order to obtain a large number of micropores on the chromium layer to improve the corrosion resistance of the coating, how should the electroplating solution for nickel sealing grooves be properly maintained and managed?
When we use nickel sealing additives to produce, to obtain a good nickel sealing coating, the preparation sequence of the plating solution is very important.So how should the plating solution be prepared?
In our production process using nickel plating additives, the plating solution is often contaminated by copper ion impurities, especially the plating solution produced by barrel nickel plating.So where do these copper ion impurities come from?
When we use electroplating nickel additives, sometimes the anode plate will be passivated, resulting in fogging of the nickel plating layer and a decrease in brightness.So, what are the phenomena of anode plate passivation?
In our daily nickel-chromium plating process, sometimes the coating of the workpiece is flowered after chrome-plating, which will affect the appearance quality of the coating.Is this blooming caused by improper use of our nickel plating brightener?
