Abstract

PURPOSE:To form a nonmagnetic Ni-P-Mo plating film by jointly using >=2 kinds of dicarboxylic acids or their salts as the complexing agent of an electroless plating bath. CONSTITUTION:A complexing agent is added to an Ni-P-Mo electroless plating bath contg. 4-8g/l of a water-soluble nickel, 0.01-1g/l of a water-soluble molybdate and further hypophophorous acid or its salt. Two or more kinds of dicarboxylic acids or their salts are jointly used as the complexing agent, and an oxydicarboxylic acid or its salt is used as at least one kind. Consequently, an Ni-P-Mo plating film capable of maintaining non-magnetism even when heat-treated at 300 deg.C for 3hr is deposited at a high rate with a good throwing power of electrolytic coloring.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As a non-magnetic plating film, a Ni-P film is well known. This Ni-P coating is an electroless Ni-based alloy containing water-soluble nickel salt, complexing agent, hypophosphorous acid or its salt as a main component.
It is obtained by using a P plating bath and has the advantages of uniform deposition, high corrosion resistance, high hardness, high wear resistance, etc., but when heat-treated at a temperature of 200 ° C. or higher, it is easily magnetized. For this reason, it has been attempted to increase the P content in the Ni-P coating by increasing the concentration of hypophosphite ions in the electroless Ni-P plating bath. There is room.
