Nickel is the all-rounder of surface technology. With its diverse properties, nickel is one of the most important and frequently used coatings because it is almost universally applicable. Nickel layers are characterised by high resistance to atmospheric corrosion, many acids, sea water and alkali solutions. Chemical resistance is increased by the formation of an oxide layer. Nickel is also valued for its tribological benefits, such as wear resistance and slipperiness. Its silvery white look that has a slightly yellowish tone, which can be adjusted from matt to glossy, is ideal for decorative applications. Depending on the requirements, nickel can be deposited electrochemically or chemically. Both coating processes generate their own specific properties, which do not compete with each other, but complement each other in technical and economic terms. Glossy nickel Glossy nickel (mirror gloss) is preferred for highly decorative surfaces and is used as an intermediate layer for glossy chrome plating, which can be changed back to matt with intermediate polishing. Layers are used very often in the sanitary industry. At 650 HV, nickel layers are relatively hard and tough. Sulfamate nickel Sulfamate nickel is a purely technical nickel process in which very ductile nickel layers are deposited (due to the low internal stresses), which can be easily reshaped. Typical applications are rivets and sheet metal parts that are then crimped.
