According to the aluminum alloy, the elements such as chromium, vanadium and molybdenum are added into the aluminum alloy, and thus the mechanical property of the aluminum alloy is greatly improved; the aluminum alloy has the advantages of being high in strength, high in tenacity, extremely good in abrasion resistance, good in corrosion resistance and the like.
Description
Technical field
The present invention relates to a kind of aluminium section bar, be specifically related to a kind of anticorodal aluminium alloy containing molybdenum element.
Background technology
Aluminium alloy is a most widely used class non-ferrous metal structured material in industry, widely applies in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry.The density of aluminium alloy is low, but its strength ratio is higher, close to or exceed high-quality steel, plasticity is good, can be processed into various section bar, has excellent electroconductibility, thermal conductivity and corrosion stability, industrially widely uses, and usage quantity is only second to steel.But, the wear resisting property, the corrosion resistance that are mostly exposed to outdoor aluminum product are not at present all very desirable, especially the aluminum door and window used in people's daily life, the aluminum railing, handrail etc. of public place are in the environment of exposing to the weather and drenching with rain all the time, be corroded, be oxidized so the situation of fracture damage very serious, greatly shorten its work-ing life.
Summary of the invention
The object of the invention is to the some shortcomings for existing in prior art, providing a kind of high strength, good toughness, super abrasive, the aluminium alloy that erosion resistance is good that improve alloy mechanical property by adding the elements such as chromium, vanadium, molybdenum.
To achieve these goals, present invention employs following technical scheme:
A kind of anticorodal aluminium alloy containing molybdenum element, by mass percentage, the described anticorodal aluminium alloy containing molybdenum element contains: chromium 4 ~ 8%, copper 1 ~ 2%, magnesium 0.2 ~ 0.4%, zinc 0.4 ~ 0.8%, molybdenum 3 ~ 5%, vanadium 0.2 ~ 0.3%, bismuth 0.02 ~ 0.03%, nickel 2 ~ 5%, silicon 0.5 ~ 0.6%, cadmium 0.5 ~ 1%, tin 0.2 ~ 0.4%, surplus are aluminium and impurity.
Preferred further to technical scheme of the present invention, by mass percentage, the described anticorodal aluminium alloy containing molybdenum element contains: chromium 6%, copper 1%, magnesium 0.3%, zinc 0.5%, molybdenum 4%, vanadium 0.3%, bismuth 0.02%, nickel 4%, silicon 0.6%, cadmium 0.8%, tin 0.3%, surplus are aluminium and impurity.
Further illustrate, described impurity comprises carbon, phosphorus, the sulphur of trace.
Aluminium alloy of the present invention adopts conventional production process: raw material is carried out just refining by (1); (2) refining; (3) cooling forming; (4) rolling; (5) quench; (6) tempering; (7) cool.
Carry out some to the performance of some component elements that the present invention adopts below to introduce:
Chromium (Cr), chromium can improve hardenability and the tempering resistance of aluminium alloy effectively, improve the intensity of aluminium alloy, and chromium can also reduce the activity of carbon, improve the leaching carbon of aluminium alloy, and form fine carbide, the aluminium material surface decarburization in heating, rolling and heat treatment process and greying tendency can be reduced, improve toughness and wearability; But, during chromium too high levels, form the carbide of chromium on the contrary in a large number, worsen bullet subtractive energy and the toughness of aluminium alloy.Therefore, in the present invention, the content controlling Chromium in Aluminum Alloy is 4 ~ 8%(weight percent), most preferred content is 6%.
Molybdenum (Mo), molybdenum is the key element of aluminum alloy corrosion resistant; Therefore, the performance of molybdenum additives on aluminium alloy has very large impact, and a small amount of molybdenum is added among aluminium alloy, and aluminium alloy can be made to have very excellent performance, greatly can increase the wear resisting property of aluminium alloy, increase the service life.Aldural can improve aluminium hardness, intensity and toughness containing molybdenum, and the good weldability of tool and corrosion resistance.After foundry goods adds the molybdenum of 1% ~ 2%, will greatly improve tension, bending resistance and fatigue resistance, also can improve the homogeneity of casting structure, this especially seems important to massive casting, these foundry goods are widely used in automobile making, pressure pipeline and mold etc., and in processing industry, molybdenum is used more extensive.Utilize thermal expansivity little, heat conduction be strong, molybdenum that high strength is good or molybdenum base alloy, die life significantly extends; Add the performance that alloying element just can improve them in Xiang Tie, aluminium and other metal, as hardenability, under intensity, erosion resistance and resistance to abrasive property.But during the too high levels of molybdenum, then worsen the plasticity of aluminium alloy, toughness and processing characteristics.Therefore, in the present invention, the content that contriver controls molybdenum in aluminium alloy is 3 ~ 5%(weight percent), optimum optional 4%.
Vanadium (V), has physicals and the chemical property of numerous excellence, and thus the purposes of vanadium is very extensive, has the title of metal " VITAMIN ".In aluminium alloy, add vanadium, can grain coarsening temperature be improved, thus play the intensity, toughness and the wear resistance that increase aluminium alloy.In the present invention, the content controlling vanadium in aluminium alloy is 0.2% ~ 0.3%, and optimum content is 0.3%.
Nickel (Ni), nickel has good over-all properties, can resistance to various acid corrosion and stress corrosion, and property is tough and tensile, is magnetic and good plasticity-, and welding property might as well; Under 650 ~ 1000 DEG C of high temperature, have higher intensity and anti-oxidant, resistance to combustion gas corrosion ability, be most widely used in superalloy, that hot strength the is the highest class alloy.In the present invention, the content controlling nickel in aluminium alloy is 2% ~ 5%, and optimum content is 4%.
Advantage of the present invention:
Aluminium alloy of the present invention is by adjusting composition and the proportioning of the composition of alloy, not only with the addition of the elements such as copper, magnesium, silicon, zinc, also added the elements such as chromium, vanadium, molybdenum, nickel, pass through high melt, stable strengthening phase can be formed, greatly improve mechanical property and the welding property of aluminium alloy; Aluminium alloy of the present invention is more wear-resisting, erosion resistance better, and work-ing life is also longer.
