Ytterbium-added nickel-phosphorus alloy electroplating bath

◇Characteristics: Ytterbium ion and ammonium bifluoride are added to the electroplated nickel phosphorus alloy. Ions make the solution efficient and stable, and ammonium bifluoride plays a better buffering effect, keeping the pH value of the solution constant, so the obtained coating is uniform and dense, with the advantages of high hardness and good corrosion resistance.

◇Usage and usage This product is mainly used for electroplating nickel-phosphorus alloy liquid.

The method of using electroplating nickel-phosphorus alloy solution is to adjust the pH value of the electroplating solution to 2.0-4.0 with 5%-10% dilute sulfuric acid, the best pH value is 2.5-3.5, and then heat the electroplating solution to 50-75 ℃, the best constant temperature is 55-65℃, put the workpiece, where the cathode is the workpiece, the anode is nickel metal, and the cathode current density is 1-2A/dm2.
