Abstract
The invention discloses a tin-cobalt alloy decorative chromium-substituted electroplate liquid and an electroplate method thereof. The electroplate liquid consists of the following components: 40-50 g/L of stannous chloride, 30-40 g/L of cobalt chloride, 60-90 g/L of potassium chloride, 10-12 g/L of EDTA disodium salt, 5-10 g/L of sodium potassium tartrate tetrahydrate, 0.2-0.5 g/L of crylic-2-ethyl hexyl ester, 0.1-0.2 g/L of benzalacetone, 0.1-0.2 g/L of polyoxypropylene glycerol ether and 0.02-0.05 g/L of coumarin. Compared with the electroplated coating obtained by the present tin-cobalt alloy electroplate liquid, the coating obtained according to the invention is closer to a chromium coating in apperance, can be widely applied to decorative chromium-substituted technique, and has the advantages of smoothness of the electroplated coating, uniformity and compactness, good adhesive force, long service life of the electroplate liquid and the like.
Description
Technical field
The present invention relates to the ornamental chromium replacement electroplating liquid of a kind of tin-cobalt alloy electroplate liquid and electro-plating method, especially tin-cobalt alloy and electro-plating method thereof.
Background technology
Up to the present, also do not have a kind of metal or alloy coating on outward appearance and performance, can replace sexavalent chrome coating fully, only can according to the particular requirement of using, select a kind of suitable metal or alloy coating to substitute now.In the nickel-base alloy coating of now having reported, come minute from coat properties, can be divided into Alloy Plating, metal and nonmetal composite bed, inorganic generation the chromium layer and organic generation chromium layer etc.From the practical situation of electroplating industry, can be divided into two classes to nickel-base alloy coating: a class is the coating that replaces decoration chrome plating, requires the appearance of this class coating as far as possible near the blue silvery white outward appearance of the band of decorative chromium; Another kind of is the coating that replaces functional chromium plating, requires the hardness of this class coating and wear resistance will approach or surpass hard chromium, for the coating that replaces decoration chrome plating, common are tin-cobalt alloy and electroplates.And the tin-cobalt alloy that prior art obtains is only on the small workpiece, particularly just can obtain blue silvery white outward appearance near decorative chromium on the barrel plating technique small workpiece, therefore, the scope that existing tin-cobalt alloy electroplating technology replaces traditional decoration chromium is narrow, can't replace decoration chrome plating technique fully.
Summary of the invention
The purpose of this invention is to provide a kind of ornamental chromium replacement electroplating liquid of tin-cobalt alloy and electro-plating method thereof that decoration chrome plating technique can be replaced in appearance fully, be applicable to complex-shaped workpieces.
The present invention adopts following technical scheme to achieve these goals:
The ornamental chromium replacement electroplating liquid of a kind of tin-cobalt alloy, its electroplate liquid formulation consists of:
Wherein, main salt is tin protochloride and cobalt chloride, and muddiness will occur the acid tin plating liquid non-stop run two weeks take tin protochloride as main salt, is difficult to plate out qualified product, need add certain stablizer.Seignette salt (C4O6H4KNa) has complexing, can in basic solution, form soluble complexes with metal ions such as aluminium, beryllium, cadmium, cobalt, molybdenum, niobium, lead, nickel, palladium, platinum, rhodium, antimony, tin, tantalum, tungsten, zinc, (copper) and selenium, telluriums, disodium ethylene diamine tetraacetate is a kind of complexing agent commonly used, is used for complexation of metal ions and separating metal.The composite complexing agent of electroplating as tin-cobalt alloy of these two kinds of materials there is not yet report, and in the quantity-produced situation, the plating bath that adds this complexing agent compound can keep the above time of half a year limpid not turbid, has obviously prolonged the work-ing life of existing tin-cobalt alloy electroplate liquid.
Matrix is deionized water.
For the Deposit appearance that makes the tin-cobalt alloy electroplate liquid closer to decorative chromium coating, in electroplate liquid, add brightening agent, brightening agent by key light agent, auxiliary brightener, the carrier brightening agent is composite makes, the present invention selects ethyl acrylate as the key light agent.
Because the key light agent all can only be brought into play the light effect in a certain current density range, so use separately and can not obtain desirable coating, if but and auxiliary brightener just be used and can play synergistic effect, thereby coating crystallization refinement, bright current density zone are further enlarged, the present invention adopts benzylideneacetone can significantly widen the light district as auxiliary brightener and the composite use of ethyl acrylate key light agent, effectively eliminates the white mist of coating.
Simultaneously, the light effect main manifestations of organic brightening agent is the absorption on negative electrode, and the absorption on the negative electrode is crossed by force or a little less than crossing all can't obtain desirable bright coating.Because adsorb too by force, the desorption current potential is too negative, and liberation of hydrogen is serious, easily forms pin hole; In the time of a little less than adsorbing, the relative calibration of desorption current potential, the coating crystallization is coarse.Only have suitable absorption just can reach good brightness effect.The solubleness of most of organic brightening agents in water is very little, thereby the amount that is adsorbed at negative electrode is also few, so should not add separately plating bath; Some organic brightening agent in electroplating process because the reactions such as oxidation, polymerization occur, from plating bath, separate out easily, therefore, if the effect of brightening agent is not fully exerted, just must add some tensio-active agents, utilize its solublization to improve the content of brightening agent in plating bath, these tensio-active agents are called the carrier brightening agent, also be called dispersion agent, the present invention adopts polypropylene glycerol aether as the carrier brightening agent.Because polypropylene glycerol aether itself belongs to tensio-active agent, it also has wetting and the function such as crystallization of refinement simultaneously, has the interfacial tension that reduces between solution and negative electrode, makes bubble hydrogen break away from easily cathode surface, thereby prevents that coating from producing the unusual effect of pin hole.
Conducting salt is selected Repone K, in order to improve the electric conductivity of plating bath, the content of conducting salt is subject to the restriction of solubleness, and the existence of a large amount of conducting salts also can reduce the solubleness of other salts, for the solution that contains more tensio-active agent, too much conducting salt can reduce their solubleness, makes solution issue the turbid phenomenon of lactogenesis in lower temperature, serious meeting affects the performance of plating bath, so the content of conducting salt also should be suitable.
Leveling agent adopts tonka bean camphor, and this material has the effect that coating is filled and led up the trickle uneven place of matrix surface, and tonka bean camphor use as leveling agent in chromium plating there is not yet report.
The electro-plating method of the ornamental chromium replacement electroplating liquid of tin-cobalt alloy, it is characterized in that: put into electroplate liquid with stainless steel as anode, workpiece is cleaned and activates rear Bright Nickel Electroplating according to routine plating pre-treatment, the above-mentioned workpiece of electroplating bright nickel is put into the ornamental chromium replacement electroplating liquid of described tin-cobalt alloy as negative electrode, be that 50-60 ℃, pH value are 8.0-9.0 in temperature, cathode current density is 0.3-1.0A/dm
2Condition under electroplate.
The invention has the beneficial effects as follows: Deposit appearance light, be blue silvery white, exactly like the outward appearance of decorative chromium, can be widely used in ornamental generation chromium process; And the advantage such as coating polishing, even compact, sticking power are good, electroplate liquid long service life that the present invention has.
