Abstract

Electroless nickel-phosphorus plating with greater than 9% phosphorus on high purity aluminum-magnesium alloy substrates can be achieved by first depositing an electroless "strike" layer of nickel-phosphorus with approximately 5% phosphorus. After the "strike" layer has been applied, the parts can be transferred to an electroless plating bath having a greater phosphorus concentration of 9% or more. Plating there continues to the desired thickness.
