Electroless Nickel (EN) is the deposition of a Nickel alloy without the use of an electrical current. EN utilizes an autocatalytic chemical reaction, resulting in reliable, repeatable coating with uniform thickness. EN demonstrates excellent corrosion protection, with similar lubricity properties to electroplated chromium. EN effectively coats parts with sharp edges, deep recesses, seams, threads, and complex geometries. Variations of EN bath chemistry include: High, 10% to 13% Phosphorus, for applications that need superior corrosion protection; Medium, 5% to 9% Phosphorus, for general use applications; Low, <5% Phosphorus, for applications that need a hard a hard, wear and alkaline resistant coating; Nickel Teflon, for increased lubricity and reduction in friction. EN can also be rendered non-magnetic, making it the optimal choice for electromagnetic shielding.
