Electroless nickel plating is a process that code posits a nickel-phosphorous alloy without need for an externally applied electrical current. The Electroless Nickel Plating - Interconnect Components electroless nickel plating process occurs from a chemical reduction of the nickel ions within the electroless nickel solution onto a metallic substrate rather than deposition of the ions from an applied current. As a result, the electroless nickel deposit is free of many of the problems associated with traditional electrolytic nickel including edge buildup and non-uniform coating. Electroless nickel deposits are extremely uniform, corrosion and erosion resistant and provide excellent lubricity.
According to Military specification MIL-C-26074E, Electroless Nickel Plating is of commonly specified Class 1 & Class 2.
- MIL-C-26074E - Class 1: As plated, no subsequent heat treatment. A bake for hydrogen embrittlement relief is not considered a heat treatment.
- MIL-C-26074E - Class 2: Neat treated to obtain required hardness. May be used on all metals not affected by heating to 500 0F and above.
