Abstract
Thin layers of aluminum and palladium are deposited and annealed to produce aluminum-palladium alloy. The surface of the alloy is exposed and treated with an aluminum enchant to produce a catalytic surface. The catalytic surface is used for electroless plating of nickel, providing excellent plating uniformity and adhesion, as well as a reduced plating induction time. Several variants of the basic method are shown.
