Electroless Nickel Plating Services in Texas, California, & Iowa
Electroless nickel plating (ENP) is an autocatalytic chemical reduction process used to deposit a nickel-phosphorus alloy onto a metal surface without requiring electricity. Unlike electroplating, which relies on an external power source, ENP uses a chemical bath reaction to achieve a uniform, corrosion-resistant, and wear-resistant coating.
This versatile plating process can be applied to both metallic and non-metallic surfaces, making it ideal for precision components, industrial machinery, and high-performance applications. With ENP, even intricate shapes and internal surfaces receive a consistent, even coating.
Electro-Coatings’ electroless nickel plating services comply with industry standards, including:
- ASTM B733
- Mil-C-26074E
- AMS 2404B & AMS 2404E

How the Electroless Nickel Plating Process Works
The ENP process follows several key steps to ensure durability, adhesion, and uniformity:
1. Pre-Treatment & Cleaning
Before plating, the component undergoes degreasing and chemical cleaning to remove contaminants, ensuring a strong bond between the base metal and nickel-phosphorus layer.
2. Chemical Bath Immersion
The component is submerged in a carefully controlled nickel-phosphorus bath, where the autocatalytic reaction evenly deposits the coating onto all surfaces.
3. Phosphorus Content Control
The level of phosphorus in the bath determines the plating’s characteristics, such as corrosion resistance, hardness, and friction properties.
4. Post-Treatment & Finishing
After plating, components may undergo heat treatment to enhance hardness or polishing for improved aesthetics.

Benefits of Electroless Nickel Plating
Components used in industrial applications often encounter punishing conditions. Electro-Coatings provides five different types of electroless plating, and though they are mainly dependent on the amount of phosphorus present in the chemical bath, they each provide unique on-the-job performance advantages. These unique advantages include wear/corrosion resistance, friction resistance, and the uniformity of the coating.

Levels of Phosphorus in Electroless Nickel Plating
As mentioned above, there are different types of electroless nickel that are used for electroless nickel plating that contain varying levels of phosphorous – low, medium and high – for different applications.
The most commonly used type of electroless nickel contains medium levels of phosphorus, also called MPEN. MPEN contains anywhere from 5% and 9% phosphorus. Processes using this type of EN have high-speed deposit rates as well as bright and semi bright options. Low phosphorus electroless nickel (under 5% phosphorus) provides parts and configurations with uniform thickness on the inside to eliminate grinding after plating has been completed as well as alkaline corrosion resistance. Electroless nickel with highest amounts of phosphorus – anywhere from 10% to 13% - are used in oil drilling and coal mining and other applications where a high level of corrosion resistance is needed for protection against highly corrosive acids.

Why Choose Electroless Nickel Plating (ENP)?
Electroless nickel plating provides large flexibility of thickness and volume of the plating on metal services can easily fill recesses or pits in the metal services. This allows for a wider variety of industrial parts that can be finished with a uniform surface, including oil field valves, valve pumps, driveshafts, electrical/mechanical tools, and engineering equipment.
What is the difference between nickel plating and electroless nickel plating?
Electroless nickel plating is less porous than electroplated nickel and provides a barrier of corrosion protection to steel. It can be applied with zero or little compressive stress making it gentle in application.
Is electricity required for electroless nickel plating?
No electricity is required for ENP, making it a more accurate and efficient and cost-effective coating process. It can be completed with less equipment and fewer coats than electroplating to create a stronger, high-quality finish.
What is the hardness for electroless nickel plating?
Electroless nickel plating has a hardness of between 68 and 72 on the Rockwell C Scale.
