PALLADIUM/IRON ALLOY PLATING SOLUTION AND PALLADIUM ALLOY PLATED BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a palladium alloy plating solution capable of applying white, bright plating good in glosiness, white and beautiful and excellent in corrosion resistance and thickening property instead of nickel plating having anxity of inducing metal allergy. ;SOLUTION: By a palladium/iron alloy plating solution containing conductive salt of 5 to 30 g/L, containing a soluble iron compound of 0.01 to 10 g/L expressed in terms of metallic iron, containing a soluble palladium compound of 1 to 30 g/L expressed in terms of metallic palladium, containing free ammonia of 1 to 50 g/L and a brightener of 0.1 to 30 g/L and whose pH is controlled to 7.0 to 12.0 by alkali hydroxide, white, bright plating which does not induce metal allergy, is beautiful in appearance and good in corrosion resistance can be obtained.;COPYRIGHT: (C)2001,JPO
