Description
Technical field
The present invention relates to a kind of copper process of surface treatment.
Background technology
Copper and copper alloy are in human history, to use one of metal material the earliest. Copper alloy toolHave high electric conductivity, thermal conductivity, corrosion resistance and good formability, be widely used in electric power,Electrician, mine, metallurgy and machinery manufacturing industry. But the hot anti-wear performance of copper alloy surface is poor,In engineering application, usually needing to carry out surface applies or modification.
Copper belongs to semi-precious metal, compared with equilibrium hydrogen electrode, has the current potential of calibration, but and oxygenElectrode potential is compared, more negative again. So may carry out negative electrode oxygen uptake corruption under most of conditionsErosion, and can not from acid, separate out hydrogen. In the time that in acid, alkali, anaerobic agent exists, copper comparisonAnti-corrosion; When containing oxidant, copper corrodes.
Copper corrosion is divided into chemical attack, electrochemical corrosion and physics corrosion by process. Chemistry is rottenErosion is the surperficial destruction that directly electrochemical action occurs with surrounding medium and cause of copper. In corrosionIn process, the transmission of electronics is directly carried out between copper and oxidant. Electrochemical corrosionBe the destruction that copper surface produces with the dielectric generation electrochemical reaction of ionic conductance, be alsoThe most general, the modal corrosion of one is also a more serious class corrosion simultaneously. Copper existsThe corrosion overwhelming majority in atmosphere, seawater, soil, acid, alkali, salt medium is electrochemistry corruptionErosion. Electrochemical corrosion can with machinery, mechanics, biological destruction acting in conjunction, aggravation goldBelong to the loss of copper. Physics corrosion refers to that copper is due to the caused destruction of simple physical action,This class corrosion proportion is less.
Fine copper has very high thermal conductivity, electric conductivity and corrosion stability, in metallurgical industry and petrochemical industryIn industry, be used widely. For example use fine copper manufacture air port in blast furnace, cinder notch,Knot in cooling wall, Oxygen Lance Nozzle for Converter, steel billet thermal cutting burning torch burner, steelmaking continuous casting machinesBrilliant device and some chemical device elements etc. Working environment one side and the high-temperature liquid of these partsBody or gas medium directly contact, and another side contacts with the cooling medium such as water or gas. ButBe, the high temperature oxidation resistance of fine copper is poor, and hardness is low, not wear-resisting. With fine copper make air port,Cinder notch and crystallizer etc. are easy to lose efficacy damage under the washing away, wear and tear of high temperature liquid iron, molten steel.The life problems of metallurgy industry heat transfer copper product is a global difficult problem, and is all exerting countries in the worldPower solves. Be considered at present the good technology of effect and mostly be surface reinforcing method, comprising:Alloy plating, alloying and built-up welding heat-resisting alloy, in addition also have thermal spraying heat insulating coat andInlay the processes such as ceramics. Traditional processing method effect is bad, and processing need to be higherCost, and its performance of the workpiece of handling well can not reach requirement, therefore a kind of improvement of urgent needTechnology solve above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of copper process of surface treatment.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of copper process of surface treatment, comprises the following steps:
(1) adopt the mode of mechanical cleaning and Chemical cleaning to carry out cleaning treatment to surface of the work;
(2) workpiece is carried out to blasting treatment;
(3) workpiece oxygen barrier is heated to 520-560 DEG C, keeps temperature, workpiece immersion is meltedIn aluminium liquid, by its taking-up;
(4) workpiece is cooling rapidly;
(5) work-piece cools is carried out bead to workpiece to normal temperature;
(6) workpiece surface spraying hole sealing agent;
(7) workpiece is added in heat-treatment furnace to thermal diffusion.
The time that workpiece immerses in aluminium liquid is 1-2min.
DIFFUSION TREATMENT is carried out in the heat treatment of atmospheric environment, heating-up temperature 750-820 DEG C, temperatureDegree keeps 3-6 hour, naturally cooling.
The invention has the beneficial effects as follows: technical process is simple, easy to operate, actual production becomesThis is less, and its case hardness of workpiece that uses the present invention to make is high, and wearability is strong, corrosion-resistantProperty strong, be easy to promote.
