Characteristic
Chemical nickel plating (alloy Ni+P) is included among the function coatings. Nickel expelled by autocatalysis makes it possible to coat parts with a complex shape, as well openings and edges. The nickel coating is of a uniform over the entire surface of the part (and does not require any further sanding). It partially replaces the technology of hard chrome plating, because the heat treatment increases the temper.
Properties of the coating
- high resistance to corrosion of the virtually non-porous surface (at the thickness of 10 µm or more)
- uniform thickness of the coating
- attractive appearance (semilustrous to lustrous)
- high temper – after heat treatment (usually 800 +/- 50 HV)
- smooth surface providing minimal friction
Thickness of the coating
- usually up to 20 µm
- in exceptional cases up to 50 µm
Base material
- steel, cast iron, aluminum and non-ferrous metals
Uses
- machine, automotive, aviation and chemical industries
- parts for pump equipment, compressors, hydraulic machines
- parts for nuclear industry and electronics
