What is Nickel Plating?
A method of plating a layer of nickel on a metal or some non-metal by electrolysis or chemical method is called nickel plating. Nickel plating is electroplated with nickel and electroless nickel plating. Nickel plating is in an electrolyte consisting of a nickel salt (called a main salt), a conductive salt, a pH buffer, a wetting agent, a metal nickel for the anode, a cathode for the plating, and a direct current, on the cathode (plated). A uniform, dense nickel coating is deposited on top of it. Obtained from the plating solution to which the brightener is added is bright nickel, and in the electrolyte without the brightener added, dark nickel is obtained.
Electroless plating, also known as electroless plating, can also be called autocatalytic plating . The specific process refers to a process in which metal ions in an aqueous solution are reduced by a reducing agent under a certain condition and precipitated onto the surface of a solid substrate. ASTM B374 (ASTM, American Society for Testing and Materials) is defined as Autocatalytic plating is "deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloy being deposited". This process is different from displacement plating, the coating can be continuously thickened, and the metal plating itself has catalytic ability.
