Metal alloy electroplating liquid

Abstract

The invention discloses a metal alloy electroplating liquid. The metal alloy electroplating liquid is composed of the following raw material components in parts: 30-40 parts of copper sulphate, 30-50 parts of aluminium sulphate, 50-60 parts of copper chloride, 50-60 parts of nickel hydroxide, 20-30 parts of cobalt sulphate, 30-40 parts of cobalt chloride, 10-15 parts of iron sulphate, 30-35 parts of ferrous chloride, 50-58 parts of cuprous oxide, 16-18 parts of hydrochloric acid, 15-20 parts of acetic acid, 3-4 parts of Tween-60, 4-5 parts of sodium hydroxyethyl sulfonate, 5-6 parts of allyl polyethenoxy ether, 6-7 parts of polyethylene glycol, 3-4 parts of ammonium lauryl sulphate, 5-8 parts of sodium lauryl sulphate and 200-300 parts of deionized water. The metal alloy electroplating liquid is good in stability, the surface of a plated film is high in brightness and smoothness, the flexibility of a plated layer is obviously improved, and the defects of burrs, roughness and the like on the outer surface of a plated part are basically eliminated.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a metal alloy electroplating solution. Background technique [0002] At present, the alloy electroplating layer has superior physical and chemical properties. Compared with the traditional nickel plating process, the nickel-iron alloy electroplating uses cheap pure iron to replace part of the expensive metal nickel, so that harmful iron impurities become in the coating. The beneficial ingredients not only reduce the cost of electroplating, but also reduce the disadvantages of pinholes and brittleness of the coating. However, alloy plating has a problem with solder wettability, and therefore has low reliability after brazing, and cannot be put to practical use. In addition, in the plating process, the cathodic current efficiency is poor, the plating speed is slow, and the obtained plated particles are rough and have problems in appearance such as dullness.

However, alloy plating has a problem with solder wettability, so the reliability after brazing is low, and it cannot be practically used.

In addition, in the plating process, the cathode current efficiency is poor, the plating speed is slow, and the obtained plated particles are rough, and there are problems in appearance such as dullness.
