Title: Method for electroless-plating aluminum or aluminum alloy
Inventor: GOTOU SHIGEYUKI
IPC: C23C18/36
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To uniformly form a zinc film on the whole surface of a substrate and to uniformly form an Ni-P film on the whole surface of the substrate by drying an Al or Al alloy and then applying zincate conversion. SOLUTION: Zincate conversion is first applied to an Al or Al alloy, and then electroless Ni-P plating is conducted. In this case, the Al or Al alloy is degreased 31, washed with water 32, etched 33, washed with water 34, dried 35, subjected to zincate conversion 36, washed with water 37 and then electroless-plated with Ni 38. The Al or Al alloy is dried 35 in an atmosphere at room temp. to 200 deg.C until the free water on the surface is vanished. Accordingly, since free water is not present on the whole surface of the Al or Al alloy in the zincate conversion 36, zinc is uniformly deposited on the whole surface, and a uniform zinc film is formed.
