  • When using zinc nickel alloy brightener for production, the nickel content in the coating is on the high side, which should be noted

    When using zinc nickel alloy brightener for production, the nickel content in the coating is on the high side, which should be noted

    In the process of using zinc nickel alloy brightener, we need to control the concentration of zinc ion, nickel ion and sodium hydroxide in the bath to obtain protective zinc nickel alloy coating with high decorative and corrosion resistance.Sometimes the nickel content in the coating of the workpiece is too high. What causes this?

  • Control of initial and final reaction of plating solution in the production process of using medium phosphorus electroless nickel plating solution

    Control of initial and final reaction of plating solution in the production process of using medium phosphorus electroless nickel plating solution

    When we use medium phosphorus electroless nickel plating solution for production, there is such a phenomenon: the nickel layer will produce by-products of phosphite during the deposition process. With the production, the concentration of phosphite will become higher and higher, so the reaction rate of electroless nickel plating will be affected and gradually reduced.The deposition rate of the plating solution at the initial and final stages will have a large deviation, so how can we reduce this deviation?
