1. Corrosion resistance and corrosion protection
One of the most common reasons for the use of electroless nickel coatings in functional applications is its excellent corrosion resistance. In the very corrosive conditions encountered in drilling and producing oil wells, for example, electroless nickel has the ability to withstand the combination of corrosive chemicals and abrasion.
2. Wear resistance
With the appropriate heat treatment, electroless nickel plating can be hardened up to 950vhn. This makes it ideal for areas exposed to friction and wear.
A great feature of electroless nickel plating is its hardness. Hardness values for electroless nickel deposits are in the range of 450-750 VHN, depending on the phosphorous content of the deposit.
Electroless nickel plating has natural self lubricating properties, which eliminates the need for liquid lubricants on components.
5. Solderability and bondability
Electroless nickel-phosphorus alloys are easily soldered with a highly active acid flux.
6. Uniformity of deposit regardless of geometries
Electroless nickel plating has a completely uniform coating. It’s a perfect solution for critical high-end engineering items including defence, healthcare, automotive and aerospace. Electroless nickel can be deposited to produce a wide range of coating thicknesses, with uniformity and minimum variation from point to point.
This uniformity can be maintained in plating both large and small parts and on components that are fairly complex, with recessed areas. Electroplating of such parts, on the other hand, would produce thickness variation and possible voids in the plating when coating holes and inside diameters.
7. Nonmagnetic properties of high-phosphorus nickel alloy
Electroless nickel deposits containing greater than 8 percent phosphorus are considered to be essentially nonmagnetic as plated.
