Abstract
The invention discloses a high anticorrosion decorative chromium process which is characterized by comprises the following steps: a, carrying out conventional pre-treatment to the surface of a metal product; b, plating zinc-nickel alloy on the surface of the metal product; c, plating burnt phosphor copper or alkali copper; d, plating acid copper; e, plating nickel; f, plating chromium; and g, drying. Due to zinc-nickel alloy layers, copper layers, nickel layers and chromium layers, the metal product manufactured by the decorative chromium process has high mechanical hardness which can reach the hardness of the product manufactured by the traditional decorative chromium process, high anticorrosion performance more than 50 hours and high anticorrosion performance. In the premise of meeting the performance, quality and effect requirements of the traditional decorative chromium product, the decorative chromium process of the invention can reduce the time for plating the copper layers, nickel layers and chromium layers so as to reduce the cost of products. The high anticorrosion decorative chromium process of the invention is an ideal substitute for the traditional decorative chromium process.

The common metal goods are many in the life, for example, draw basket, chair pin, motorbike frame or the like.That uses always in the prior art makes various metal productss by iron or steel, and its surface all is electroplate with the zinc layer, or the decorative chromium layer.The mechanical hardness and the preservative property of the metal products of electro-galvanized layer are not enough, though and decorative chromium has more intense mechanical hardness and antiseptic property, in the traditional decoration chromium process, treatment process cost height, the products production cost of gained is also high.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of high anticorrosion decorative chromium process, and the metal products that this kind decorative chromium process draws has than higher antiseptic property, have than higher hardness, and the production cost of technology are low.
The present invention can take following technical scheme:
A kind of high anticorrosion decorative chromium process is characterized in that: comprise following processing step,
A, conventional pre-treatment is carried out on the metal products surface;
B, electroplated zinc nickel alloy is carried out on the metal products surface;
C, the burnt phosphor-copper of plating or alkali copper;
D, electroplating acid copper;
E, electronickelling;
F, electrodeposited chromium;
G, oven dry.
The present invention deals with problems and can also further take following measure:
Among the above-mentioned processing step b, its technology is carried out under the physical condition of routine and electrochemical conditions.
Among the above-mentioned processing step c, its technology is carried out under the physical condition of routine and electrochemical conditions.
Among the above-mentioned processing step d, its technology is carried out under the physical condition of routine and electrochemical conditions.
Among the above-mentioned processing step e, its technology is carried out under the physical condition of routine and electrochemical conditions.
Among the above-mentioned processing step f, its technology is carried out under the physical condition of routine and electrochemical conditions.
Among the above-mentioned processing step g, during oven dry, be to dry under 120～180 environment of spending in temperature.
Technique scheme has such technique effect:
1, the metal products that utilizes decorative chromium process of the present invention to obtain, owing to have admiro layer, copper layer, nickel dam, chromium layer, mechanical hardness can reach the hardness of traditional decoration chromium process product.
2, the metal products that utilizes decorative chromium process of the present invention to obtain owing to have admiro layer, copper layer, nickel dam, chromium layer, can strengthen antiseptic property, and antiseptic power can reach (employing neutral salt spray test) more than 50 hours.
3, the metal products that utilizes decorative chromium process of the present invention to obtain, has the admiro layer, the admiro layer is plated on the outside surface of matrix, the technology cost of electroplated zinc nickel alloy is low, under the cooperatively interacting of other copper layer, nickel dam, chromium layer, can reach under the situation of traditional product surface mechanical hardness and high preservative property, can reduce the electroplating technology time of copper layer, nickel dam, chromium layer, and the electroplating technology of copper layer, nickel dam, chromium layer is somewhat expensive, and then can reduce product cost.
Embodiment
Below in conjunction with specific embodiment the present invention is specifically described.
Embodiment 1: high anticorrosion decorative chromium process is characterized in that: comprise following processing step,
A, conventional pre-treatment is carried out on the metal products surface.
B, under the physical condition and electrochemical conditions of routine, electroplated zinc nickel alloy is carried out on the metal products surface.
C, under the physical condition and electrochemical conditions of routine, electroplate burnt phosphor-copper or alkali copper.
D, under the physical condition and electrochemical conditions of routine, carry out electroplating acid copper.
E, under the physical condition and electrochemical conditions of routine, carry out electronickelling.
F, under the physical condition and electrochemical conditions of routine, carry out electrodeposited chromium.
G, oven dry during oven dry, are to dry under 80～120 environment of spending in temperature.
Obtain finished product, the structure of product is respectively metal material matrix, admiro layer, copper layer, nickel dam, chromium layer from inside to outside.
In technology of the present invention, the combination of process steps of the processing step of electroplated zinc nickel alloy and the burnt phosphor-copper processing step of plating or plating alkali copper can make product have high antiseptic property.In technology of the present invention, compare with the traditional decoration chromium process, the processing step of many important electroplated zinc nickel alloys, can reduce the time of electrolytic copper technology, electronickelling technology and electrodeposited chromium technology, reducing under electronickelling technology and the situation of 70% time of copper plating process, still can reach the mass effect performance of traditional decoration chromium process product.As everyone knows, the cost of electroplated zinc nickel alloy technology is low, and the cost height of electronickelling technology or electrodeposited chromium technology is reducing under electronickelling technology or the situation of copper plating process time, can reduce the whole process flow cost, and then reduce the cost of product.
Below be the mass effect contrast table that the metal products that draws of technology of the present invention and traditional technology draw metal products,
From form, can draw to draw a conclusion:
1, the metal products that draws of treatment process of the present invention, mechanical hardness all reaches 5H, has reached the hardness of traditional decoration chromium process.
2, the metal products that draws of treatment process of the present invention, antiseptic power can reach and surpass the antiseptic power of traditional decoration chromium process greater than (taking middle salt-fog test) more than 50 hours.
3, the metal products surface brightness that draws of treatment process of the present invention is good, has mirror effect, has the surface effect of decorative chromium.
