Black nickel is created by electroplating a unique electrochemical process. As the name suggests, it deposits a thin layer of black nickel onto an electrically conductive metal substrate. A common question that arises is, “Why does nickel turn black?” The best answer is that black nickel reduces reflectivity.
The last functional bath in the KNK zamac plant in the entire galvanic surface treatment process is a black nickel solution in which an electric current is also used, which results in electrons passing through the cathode of the product and attaching to its copper layer, collecting nickel ions that are released from the nickel anodes to combine with it. In this way, the nickel ions are deposited on the surface and create a black nickel layer.
Black nickel electroplating is a premium technology in surface finishing. The deep, rich black finish adds a premium look to any metal part. It generally offers many benefits, one of which is corrosion resistance. Due to its benefits, it is widely used in many industries. In the automotive industry, you can find many automotive parts and accessories that are black nickel plated. Similar applications can be seen in electronics, home decor, and architecture. Overall, products with nickel plating have a longer lifespan. They generally remain functional and attractive for many years. You can clean them by simply wiping them with a soft cloth. The low maintenance saves time and effort.
Galvanic black nickel only works on conductive materials, which are steel, copper, brass and zinc alloy, which must be copper-plated before being applied in galvanic KNK zamac baths. Its required thickness with a deep black surface is achieved by setting a low voltage and a low direct current value for a longer time with careful placement of the anode and cathode parts.
Black nickel plating is a popular type of electroplating. The process creates a layer of black nickel on the surface of the product. This black nickel layer provides a unique, premium look. In addition, it is resistant to corrosion and wear.
