Electroless nickel plating services
Electroless nickel plating is a process that deposits an alloy of nickel-phosphorus onto the surface of a metal. This process is chemical only, so does not involve the use of electricity.
| Surface preparation | Tolerances | Cosmetic availability | Thickness | Visual appearance |
|---|---|---|---|---|
| Smooth machined (Ra 1.6μm / Ra 63μin) | Apply after Electroless nickel plating | No | 3μm to 40μm | Electroless nickel plated parts will have a smooth, semi-bright appearance. |

Design considerations for electroless nickel plating
Masking: Electroless nickel plating does not have a significant dimensional impact, therefore masking parts is not necessary.
The Protolabs Network electroless nickel plating process
Electroless nickel plating is a wear, abrasion and corrosion resistant finish that is compatible with aluminum, stainless steel and mild steel.
Here’s how to apply electroless nickel plating:
Parts are first washed and degreased to remove any contaminants, cleaning away any grease or oil
After cleaning is completed, the substrate is activated with another chemical, an acid, to remove oxides and activate the surface.
Parts are then dipped in the plating chemical solution, depositing the nickel-phosphorus alloy on the parts until desired thickness is reached
