ASTM B733, AMS 2404, MIL-C-26074

Electroless nickel plating or autocatalytic nickel plating is a widely used surface finishing process that offers several advantages over other plating techniques. Specifications for EN are ASTM B733, AMS 2404 and MIL-C-26074. Here are some of the key benefits of electroless nickel plating:

Uniform and Consistent Coating: Electroless nickel plating provides a uniform and consistent coating on complex geometries, including internal surfaces, corners, and recesses. It deposits a uniform layer of nickel onto the substrate, regardless of its shape or size, ensuring an even coating thickness.

Corrosion and Wear Resistance: Electroless nickel coatings offer excellent corrosion resistance, protecting the underlying substrate from rust, oxidation, and chemical attack. The deposited nickel layer acts as a barrier, preventing the substrate from being exposed to the corrosive environment. Additionally, electroless nickel coatings provide good wear resistance, enhancing the lifespan and durability of the treated parts.

Hardness and Surface Hardness: Electroless nickel plating can produce coatings with varying levels of hardness, ranging from relatively soft to very hard, depending on the specific formulation and process parameters. This allows the plating to meet different requirements, including wear resistance, load-bearing capacity, and dimensional stability. Electroless nickel coatings can also be heat treated to further increase their hardness and surface hardness.

Thickness Control: Electroless nickel plating enables precise control over the coating thickness. The process parameters can be adjusted to achieve the desired thickness, ensuring consistent results and meeting specific engineering requirements.

Excellent Adhesion: Electroless nickel coatings exhibit excellent adhesion to a wide range of substrates, including metals, alloys, ceramics, and some plastics. This adhesion ensures that the coating remains firmly attached to the substrate, even under harsh operating conditions or thermal cycling.

Lubricity and Low Friction: Electroless nickel plating can provide a self-lubricating surface, reducing friction and wear in sliding or rotating applications. By incorporating certain additives or incorporating post-plating treatments, the coefficient of friction can be reduced, resulting in improved performance, reduced energy consumption, and extended service life.

Versatility: Electroless nickel plating is a versatile process that can be used in various industries and applications. It can be applied to a wide range of materials, including steel, aluminum, copper, brass, and more. The plating can be customized to meet specific requirements, such as high phosphorous coatings for increased corrosion resistance or low phosphorous coatings for solderability.
