Electroless Nickel Plating

Electroless nickel is an autocatalytic chemical reaction between the substrate and nickel solution, in an aqueous solution at nearly 200°F. Electroless nickel plates without electrical current, therefore the substrate has a uniform deposit no matter the configuration of the part. Electroless nickel is deposited in tiny molecular form sealing off the substrate from the environment.

This attribute is one of many reasons why it is the most requested coating for corrosion protection. (Unlike chrome where micro cracking takes place in the deposit) Electroless nickel can evenly plate a hole as small as .020, and small grooves and deep bores are plated evenly as well. All of PFI’s electroless nickel baths are RoHS compliant.

PFI offers three electroless nickel baths

  1. High phosphorous electroless nickel for its excellent corrosion protection (salt spray test of 1000+ hours)
  2. Medium phosphorous for its hardness, brightness and fast plating rate
  3. Low phosphorous electroless nickel for its as plated RC hardness

Satin Nickel Plating

Satin nickel is excellent for corrosion protection, lubricity, and wear. Having the uniformed plating deposit and a low luster appearance makes coating most steel materials effortless. Satin nickel has a .00005 – .0002 as the most requested deposit, but a thicker deposit up to .0007 can be applied as well. Satin nickel has a plated hardness of approximately 42 – 44 RC. These attributes are some of the many reasons why satin nickel is the popular choice for corrosion protection.

Black Nickel Plating

Black nickel provides outstanding protection against corrosion and wear as a result of its uniformed plating deposit of .0003 – .001, which allows all stainless-steel materials to be coated. With a plated hardness that is approximately 54 – 56 RC, it makes a superior solution for corrosion protection as opposed to other options.
