Electroless Nickel Plating Services
Electroless nickel plating is a procedure that deposits an alloy of nickel-phosphorus onto the surface of a metal. This is chemical just, so does not entail the use of power.
ECOREPRAP Electroless Nickel Plating Service
Electroless nickel plating (ENP of NiP) is a response that deposits a nickel-phosphorus alloy onto the surface of a metal. It utilizes a totally chemical reaction to generate plating and does not take advantage of electrical power.
At ECOREPRAP, we provide electroless nickel plating as a functional surface treatment for improving wear resistance, corrosion protection, and surface hardness of precision CNC machined parts. The process deposits a uniform nickel-phosphorus alloy layer through an autocatalytic chemical reaction, without the use of external electrical current.
One of the key advantages of electroless nickel plating is its excellent thickness uniformity. Unlike electroplating, the coating is evenly distributed across complex geometries, sharp edges, internal cavities, and blind holes. This makes it especially suitable for parts with intricate features or tight dimensional requirements.
Our process includes controlled pre-treatment, activation, plating, and post-treatment steps to ensure coating adhesion and consistency. The resulting surface provides a good balance of hardness, lubricity, and corrosion resistance, and can also serve as a base for additional coatings if required.
With our machining experience, we consider factors such as tolerances, surface finish, and functional requirements to ensure the plating process integrates effectively with the final part performance.
| Surface Preparation | Applicable materials | Cosmetic availability | Thickness | Visual appearance |
| Smooth machined (Ra 1.6μm) | Steel, Aluminum | No | 3μm to 40μm | Electroless nickel plated parts will have a smooth, semi-bright appearance. |

Electroless Nickel Plating Process
Electroless nickel plating is a wear, abrasion, and rust-resistant coating that is compatible with aluminum, stainless steel, and light steel.
Here’s how to apply electroless nickel plating:
- Components are first washed and degreased to eliminate any kind of impurities, cleansing away any oil or oil.
- After cleansing is finished, the substratum is turned on with another chemical, an acid, to eliminate oxides and trigger the surface area.
- Components are dipped in the plating chemical service, transferring the nickel-phosphorus alloy on the components till the desired density is reached
Electroless Nickel Plating Design Considerations
Masking: Electroless nickel plating does not have a significant dimensional impact, therefore masking parts is not necessary.
