Abstract
By using common carbon steel plate as substrate material, one layer os copper is formed on the surface and then tieated into alloy. The present invention can eliminate the interface effect between the covered copper layer and the carbon steel substrate and raise obviously the anticorrosive, wear resisting and decorative performance of metal part. The large-scale treatment to large metal material and large-scale contimuous production can reduce production cost. In addition, the present invention can reduce environmental pollution greatly.
Description
The invention belongs to field of metal surface treatment technology, is the production technique that copper pipe, plate are covered in a kind of surface.
Copper is the metal that a kind of rose is rich in ductility, and soft and easily polishing has good electrical conductivity, thermal conductivity and ornamental, and purposes is very extensive in industry, national defence and daily life.Along with growth in the living standard, people grow with each passing day for the demand of high surface property, high anti-corrosion energy, economy, attractive in appearance and durable metallic substance.Because copper price comparison costliness, limited its application in the commercial market.Therefore, people adopt electro-plating method, cover the copper of the ornamental and protectiveness of one deck at cheap steel surface.Yet owing to have interfacial effect between copper coating and the base metal, and finally influence the corrosion resisting property of these surface-treated layers.In addition, also influenced the machining property of handling material.Along with 60-seventies electron beam, introduce in the field of metal surface treatment from bundle, laser technology, novel process for treating surface emerges in an endless stream, as laser beam (electron beam) surface modification, chemical/electrochemical deposition, chemical/electrochemical conversion, thermospray, chemical vapour deposition, physical vapor deposition, vapour phase epitaxy, rheotaxy, ion implantation, sol-gel processing, self-catalyzed deposition etc.By these surface treatment methods, can increase substantially corrosion resisting property, the Wear-resistant ability of material, give the special physics of material surface, chemical property, improve material surface integrity and ornamental.In addition, adopt these methods that the metallic surface is handled, can reduce the interfacial effect between surface-treated layer and the base metal.Amount and size that but these technical finesse costs are excessive, handle workpiece have certain restriction, therefore, can't be applied to produce by heavy industrialization.Only be used at present the field batch processes of part on a small scale such as military, aviation, thereby influence it and apply.
The objective of the invention is to propose a kind of interfacial effect that can eliminate between copper coating and the base metal, and processing cost is low, handles the production technique of the big copper-clad panel of part amount.
The production technique of the copper-clad panel that the present invention proposes comprises and selects cheap plain carbon stool plate as base material, presets layer of copper earlier on its surface, carries out Alloying Treatment then.Here so-called " plate " comprises flat board, the curved slab of certain sinuousness arranged, and also comprises tubular material etc.Its concrete processing step is as follows:
1, adopt the flash method to preset layer of copper on plain carbon stool plate surface, coating thickness is 0.01-5 μ, and its processing condition are the flash solution formula: copper sulfate 100-300g/L, sulfuric acid 60-80g/L, additive 0.01-1g/L; Electroplating temperature: 10-60 ℃; Galvanized strength of current: 1-100A/dm
2Wherein additive adopts polydithio-dipropyl semi-annular jade pendant acid sodium, polyoxyethylene glycol, sodium lauryl sulphate, and both are respectively the former 1-3 times to its weight proportion for the back.
2, the metallic substance after will handling places alloying furnace to carry out Alloying Treatment; Alloying Treatment technology is as follows: alloying is carried out under reduction protection atmosphere; wherein protective atmosphere is a nitrogen; reducing atmosphere is a hydrogen; both usage ratio are 60: 40～97: 3; be that nitrogen use level accounts for 60%～97%, hydrogen usage accounts for 60%～3%.The control of alloying temperature is as follows: be rapidly heated to the Alloying Treatment temperature, temperature rise rate is 0.01-50 ℃/S, and the Alloying Treatment temperature is 700 ℃-1000 ℃, and soaking time is 48 to 96 hours, then with the alloying furnace fast cooling to room temperature, rate of temperature fall is 0.01-50 ℃/S.Be rapidly heated and fast cooling employing usual method.
Characteristics of the present invention are:
1, the present invention can eliminate the interfacial effect between copper capping layer and the base metal, significantly improves the mechanical property of corrosion-resistant, wear-resistant, the decorate properties and the material monolithic of carbon steel.
2, the present invention can realize extensive continuous industry production, is applicable to that copper coin (pipe) material source mill carries out deep processing.
3, after the present invention realizes extensive continuous industry production, sheet metal and tubing that product cost is made far below fine copper, cheap.
4, handle back copper-clad plate material and tubing, can carry out surperficial electrolytic coloring, also can carry out processing such as surface finish, the material after the processing had both had high anti-corrosion energy, wear resisting property and surface decoration performance, have cheap advantage again, have wide practical use at industry, civil area.
5, because the flash solution formula is simple, and additive level is few, and electroplating wastewater processing is easy, environmental pollution is few, compares with common technology, helps environment protection.
