Electroplating nickel layer in the air stability is very high, crystallization is extremely small, and has excellent polishing performance, coating hardness is relatively high can improve the wear resistance of the product surface, widely used in optical instrument plating, protective decorative coating, casting mold electronic components. Electroless nickel plating Electroless nickel plating thickness uniformity, no hydrogen, no hydrogen embrittlement, no need to remove hydrogen after electroless nickel plating. Many chemical nickel plating products of corrosion resistance and high temperature oxidation resistance is better than electroplating nickel, can be deposited on the surface of various materials, don't need dc motor or control equipment for the general plating, heat treatment temperature low just under 400 ℃ after different heat preservation time, different corrosion resistance and abrasion resistance, can be obtained as a result, it is especially applicable to complicated shape, surface wear and corrosion resistant parts of functional coatings, etc. |
Nickel plating solution type
The types of nickel plating solutions are mainly sulfate, chloride, sulfamate, citrate, fluoroborate, etc. One of the sulfate type (low chloride) that is called Watts(watt) nickel plating solution in the industry is the most common application. Sulfamate type and fluoroborate type are suitable for thick nickel plating or electroforming. Citrate type is suitable for direct nickel plating on zinc die castings. The cost of these bath is higher. Other nickel plating types include: ordinary nickel plating (dark plating), bright nickel plating, aminosulfonate nickel plating, high sulfur nickel plating, nickel sealing, satin nickel plating, high stress nickel plating, multi-layer nickel plating, citrate nickel plating, etc.
