Electroless Nickel Plating
Industry Standards of Electroless Nickel Plating
With over 70 years of plating experience, Electro-Coatings offers a wide range of electroless nickel coatings based on your application's needs. Our willingness to tackle plating and coating challenges is important, but only when paired with the capability to deliver top quality results. Electro-Coatings offers both, along with the experience and facilities to deliver a product cost-effectively.
Electroless Nickel Plating Process
The process of adding an electroless nickel plating to a metal surface is an autocatalytic chemical reduction. This means that instead of using an outside source of electricity like in the similar electroplating process, the electroless nickel plating process uses a chemical bath to deposit a nickel / phosphorous layer onto the metallic surface. A surface coated in electroless nickel can even be used on non-conductive surfaces which allows for plating of a wider variety of base materials. This electroless process greatly improves the objects resistance to galling and leaves a predictable, uniform nickel coating for high-precision parts, which can be applied to both ferrous and non-ferrous surfaces of any geometry or intricate shape.
Why Choose Electroless Nickel Plating (ENP)?
Components used in industrial applications often encounter punishing conditions. Electro-Coatings provides five different types of electroless plating, and although 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. Below are some more advantages EN plating provides:
|Less porous than electroplated nickel and hard chrome.||Provides barrier corrosion protection to steel, and can be applied with zero or little compressive stress making it gentle in application.|
|No electricity required, can be completed with less equipment and fewer coats than electroplating to create a strong, high-quality finish.||A more accurate, efficient and cost-effective coating process.|
|Provides a large flexibility of thickness and volume of the plating on metal surfaces and can easily fill recesses or pits in the metal surface.||A wider variety of industrial parts to be finished with a uniform surface. Some examples include: oil field valves, pumps, drive shafts, electrical/mechanical tools and engineering equipment.|
Electroless nickel plating has long been a preferred solution for improved hardness, corrosion resistance and friction resistance in industrial applications.View Page
