Electroless nickel coatings are commonly used in engineering applications. The field of engineering often requires coatings that can withstand a lot of wear and exposure to corrosive materials.
Common applications of electroless nickel include:
- brake calipers (see image below)
- oil field valves
- door knobs
- kitchen utensils
- bathroom fixtures
- electrical tools
- mechanical tools
- office equipment
- drive shafts
- paper handling equipment
- fuel rails
Electroless nickel is the idea coating to salvage worn parts. The hardness of the coating allows continued use of the component after plating because the electroless nickel can be applied and then machined afterwards to achieve the final dimensions.
There are other hard wearing coatings of course, such as hard chromium, but electroless nickel is better suited to applications of this sort because of its uniform deposition. This means that it can be applied successfully to very complex shaped parts, with the guarantee that the electroless nickel coating will fill all recesses, holes, and irregularities of the surface with a perfectly even coating.
