Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [ 3 ] To clean and protect the part during the plating process, a combination of heat treating , cleaning, masking, pickling , and etching may be used. [ 1 ]
Black nickel plating was developed around 1905, and between the two wars, black chrome plating (first German patent 1929.GP 607, 420), which saw wider use only from the mid-1950s. [14] After the First World War, the first procedures for anodic oxidation and coloring of anodically oxidized aluminium were developed (1923, 1924.DRP. 413876).
Zinc plating was developed and continues to evolve to meet the most challenging corrosion protection, temperature, and wear resistance requirements. Electroplating of zinc was invented in 1800, but the first bright deposits were not obtained until the early 1930s with the alkaline cyanide electrolyte.
Barrel plating for electrical components (e.g. ceramic capacitors) used to grow terminals. Barrel plating is a form of electroplating used for plating a large number of smaller metal objects in one sitting. It consists of a non-conductive barrel-shaped cage in which the objects are placed before being subjected to the chemical bath in which ...
Electroless nickel plating also can produce coatings that are free of built-in mechanical stress, or even have compressive stress. [16] A disadvantage is the higher cost of the chemicals, which are consumed in proportion to the mass of nickel deposited; whereas in electroplating the nickel ions are replenished by the metallic nickel anode.
As manufacturing scales up, the facility will expand and create training and job opportunities throughout Southern California. Equatic will incorporate OSAs into Equatic-1, the upcoming demonstration-scale plant in Singapore and the first commercial-scale plant in Quebec —a facility capable of removing 109,500 tonnes of CO2 and generating ...

Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
