Abstract
The utility model relates to the technical field of materials, in particular to a copper-tin alloy plating structure. The copper-tin alloy plating structure comprises a plating substrate, and an alkaline-copper layer, an acid-copper layer and a cupronickel-tin layer are sequentially plated on the surface of the plating substrate through a method of electroplating. The thickness of the alkaline-copper layer is 15-25mum, the thickness of the acid-copper layer is 3-6mum, and preferably, the thickness of the cupronickel-tin layer is 4.5mum. Nickel metal is not contained in the copper-tin alloy plating structure, and besides metals of copper and tin, trace metals are led in, such as zinc. The plating structure is a composite multi-element metal structure so as to be stable in plating structural performance and long in service life, can achieve the effects of bright surfaces, good anti-corrosion capacity and skin allergy prevention, can replace bright nickel to serve as a decorating type plating layer, and is environment-friendly and low in cost.
Description
Technical field
The utility model relates to the material technology field, relates in particular to a kind of gunmetal electroplated structural.
Background technology
Plating is exactly to utilize electrolysis principle to plate the process of other metal or alloy thin layer on some metallic surface, thereby is to utilize electrolytic action that the technique of the surface attachment layer of metal film of metal or other material product is played to prevent that burn into from improving the effects such as wear resistance, electroconductibility, reflective and having improved aesthetic appearance.
Many workpiece (such as ornaments, wrist-watch or ornamental part, mobile phone etc.) surface all is electroplate with one deck decorative coating, to form glossy surface, thereby play, decorates or protective effect.Early stage decorative coating is generally nickel coating or chromium coating, and this kind of coating jaundice easy to change in aerobic ring mirror affects outward appearance; And, form in the electroplate liquid of above-mentioned coating and usually contain prussiate, and prussiate is poisonous, is unfavorable for process operations person's health, and be unfavorable for environmental protection; Moreover nickel often can cause allergic, therefore, for the product often contacted with human body skin, ornaments such as eyeglass leg, wrist-watch, earrings, ring, necklace, hand set machine shell, cellphone ornament etc., be not suitable for using nickel coating.
For this reason, have at present the dealer to using cu-sn alloy coating as decorative coating, this cu-sn alloy coating is generally copper-nickel alloy tin, but existing gunmetal electroplated structural poor performance makes work-ing life short, and coating surface is brightless, can turn black, and produces cloudy surface, and antirust ability is poor.
The utility model content
The purpose of this utility model is exactly the deficiency existed for prior art and a kind of surface-brightening, gunmetal electroplated structural that antirust ability is good are provided.
To achieve these goals, the technical solution adopted in the utility model is: the gunmetal electroplated structural, and it includes plating substrate, and the surface of described plating substrate is coated with alkali copper layer, sour copper layer, copper-nickel alloy tin layer successively by the mode of electroplating.
The thickness of described alkali copper layer is 15 ~ 25 μ m.
The thickness of described alkali copper layer is preferably 20 μ m.
The thickness of described sour copper layer is 3 ~ 6 μ m.
The thickness of described sour copper layer is preferably 4.5 μ m.
The thickness of described copper-nickel alloy tin layer is 0.5 ~ 2 μ m.
The thickness of described copper-nickel alloy tin layer is preferably 1 μ m.
Described plating substrate is metal material.
The utility model beneficial effect is: the utility model includes plating substrate, the surface of described plating substrate is coated with alkali copper layer, sour copper layer, copper-nickel alloy tin layer successively by the mode of electroplating, the utility model is not nickeliferous metal in electroplated structural, copper removal, tin metal have also been introduced trace metal outward, such as zinc, this electroplated structural is composite multi-component metal structure structure, make the electroplated structural stable performance, life-span is long, can produce surface-brightening, good, the anti-allergic effect of antirust ability, can replace bright nickel, as decorative coating more environmental protection and cost low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, as shown in Figure 1, the gunmetal electroplated structural, it includes plating substrate 1, and the surface of described plating substrate 1 is coated with alkali copper layer 2, sour copper layer 3, copper-nickel alloy tin layer 4 successively by the mode of electroplating.
The thickness of alkali copper layer 2 is 15 ~ 25 μ m, the thickness of acid copper layer 3 is 3 ~ 6 μ m, the thickness of copper-nickel alloy tin layer 4 is 0.5 ~ 2 μ m, in the present embodiment, the thickness of alkali copper layer 2 is preferably 20 μ m, and the thickness of sour copper layer 3 is preferably 4.5 μ m, and the thickness of copper-nickel alloy tin layer 4 is preferably 1 μ m, thickness proportion between each layer is moderate, has performance and stability preferably.
Plating substrate 1 is metal material, can be applicable on the product of various metal materials.
The utility model has increased sour copper layer 3 in electroplated structural, the not nickeliferous metal of one-piece construction, copper removal, tin metal have also been introduced trace metal outward, and such as zinc, this electroplated structural is composite multi-component metal structure structure, make the electroplated structural stable performance, life-span is long, can produce surface-brightening, good, the anti-allergic effect of antirust ability, not nickeliferous, can replace bright nickel, as decorative coating more environmental protection and cost low.
Certainly, the above is only preferred embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the utility model patent claim.
