Abstract

The invention discloses boron-tungsten-iron-nickel alloy electroplating liquid which is prepared from the following ingredients: 40-60g / L of sodium tungstate, 5-30g / L of ferrous sulfate, 20-60g / L of nickel sulfate, 2-20g / L of (dimethylamino)borane, 5-15g / L of ammonium sulfate, 36-90g / L of complexing agent, 1-8g / L of stabilizing agent, 2-10ml / L of bright additive and 1000ml of deionized water. Theelectroplating liquid does little harm to the environment, has stable process and simple ingredients, is convenient to operate and can be stored for a long term after preparation. The electroplating liquid does not exhaust acid mist during working and has high current efficiency. The plating prepared from the electroplating liquid has no microcracks on the surface and has good corrosion resistance and abrasion resistance.

Description

technical field [0001] The invention relates to an alloy electroplating solution in the field of material surface treatment, in particular to a boron-tungsten-iron-nickel alloy electroplating solution. Background technique [0002] At present, partial wear and corrosion in the field of petroleum machinery are serious, and there is no satisfactory surface treatment technology that can be used for surface treatment of petroleum machinery, which can be anti-corrosion, wear-resistant and low-cost at the same time. With the continuous consumption of petroleum resources, mining The petroleum environment is getting worse and worse, and the requirements for corrosion resistance and friction resistance of petroleum equipment are getting higher and higher. Therefore, the study of anti-corrosion and wear-resistant technology of petroleum machinery has always been a topic of people's concentration. [0003] A possible solution is to electroplate tungsten alloys. Tungsten cannot be elec...
