Nickel plating using electrolytically refined nickel as the anode

摘要

A perforated or wire mesh basket to contain pieces of electrolytic nickel as plating anode, is wholly or partly made of titanium or similar metal which is not corroded by an electrolyte of pH 4.5 or less, and which polarizes under plating conditions. Alternative metals specified are, zirconium, niobium, hafnium, tantalum, and tungsten. Vertical and horizontal frame members 21, 22, 25 are of titanium, hook members 8 are of titanium or nickel, and the perforated walls 24 may be of titanium or inert plastic. The container may be provided with an outer bag to collect falling fragments. The device may also be used in barrel plating.
