Technical field
The present invention relates to electroplate liquid technical field more particularly to a kind of alkaline composition metal alloy plating solutions and preparation sides
Method.
Background technique
With the continuous development of science and technology, the requirement of product is increasingly stringenter, the coating of single-element is difficult to meet plating
The demand of product, researcher gradually turn one's attention to alloy plating.
Plating niobium technique is widely used in the various aspects of electroplating industry, for the purpose of metal device progress anti-corrosion, decoration
Surface treatment.But since niobium resource belongs to non-renewable naturally, being continuously increased with niobium consumption figure, supply wretched insufficiency,
Cause substantial appreciation of prices.Each electroplating enterprise plating niobium cost is high.Electroplating enterprise is sought to save niobium, the new process for niobium one after another.From
From the point of view of the property of coating, the alloys such as copper niobium should become preferred plating.But there are stability for prior art copper-niobium alloys electroplate liquid
The bad, deficiencies such as electroplating efficiency is low.
Summary of the invention

Gold plating bath has that excellent stability and electroplating efficiency is high, at low cost, safety and environmental protection, be electroplated resulting tint beauty,
With good processability, can be used under wide temperature.
Specific embodiment
To further illustrate the technical scheme of the present invention in conjunction with the embodiments separately below.
Embodiment:
Prepare alkaline composition metal alloy plating liquid: complexing agent 30g and stabilizer 3g are dissolved in deionized water be made into it is molten
Polyvinyl alcohol 5g, potassium oxide 100g, mercury oxide 15g, ferroso-ferric oxide 10g, sodium chloride 5g, dioxy are added into the solution for liquid
Simultaneously mixed liquor is made in stirring and dissolving to SiClx 5g, and brightener 3g dissolution is added into mixed liquor, adds the deionized water of surplus extremely
Total volume is 1L to get to alkaline composition metal alloy plating liquid.
Electroplate liquid PH to 4~6 is adjusted with ammonium hydroxide, does anode with stainless steel, workpiece does cathode, is 50 in temperature of electroplating solution
DEG C, under the conditions of the area ratio of current density 50mA/cm2, cathode and anode is 1: 1, is electroplated, obtains bright copper niobium titanium
