Abstract

The invention discloses an environment-friendly multi-component alloy auto-catalytic plating process which includes the steps: 1) electroplating solution preparation: sequentially adding 20-30 parts of choline chloride and 50-60 parts of ethylene glycol into a beaker, stirring materials for 20-40 minutes under the heating condition of 50-60 DEG C, adding 5-10 parts of tungsten chloride and 10-15 parts of nickel chloride after the solution is transparent, continuing uniform stirring, adding 2-6 parts of tetrafluoroborate guanidine salt ionic liquid, 5-10 parts of reducing agents, 1-5 parts of dispersing agents, 1-3 parts of lactic acid, 2-5 parts of sodium acetate and 5-10 parts of complexing agents, and uniformly stirring the materials again for standby application; 2) multi-component alloy plating layer auto-catalytic treatment: heating a cleaned metal workpiece in the solution prepared in the step 1) to reach the temperature of 60-80 DEG C, and performing multi-component alloy plating. Auto-catalytic time is 10-30 minutes, and the environment-friendly multi-component alloy auto-catalytic plating process has the advantages of green and environment-friendly process, strong co-deposition capacity, excellent crocking resistance and good corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of electroplating alloy coatings, in particular to an environment-friendly multi-element alloy autocatalytic plating process. Background technique [0002] Due to the excellent performance of the coating, chemical immersion plating has the characteristics of uniform coating, small pinholes, no need for DC power supply equipment, deposition on non-conductors, and some special properties. In addition, due to less waste liquid discharge, less environmental pollution and lower cost, electroless plating technology has gradually replaced electroplating in many fields and has become an environmentally friendly surface treatment process. The chemical immersion plating process can be deposited on the surface of various non-metallic substrates such as ceramics and plastics. There is good adhesion between the coating and the substrate, and excellent corrosion resistance and wear resistance. [0003] Most of the tradit...
