Description
Technical field
The invention belongs to metal material and manufacture field, relate to a kind of method for preparing surface aluminium based composite material.
Background technology
The service life of Al alloy parts, to remove outside rigid injury, the life-span in normal use procedure is depended on surface wear performance, the decay resistance of these parts.And the abrasion resistance properties that improves Al alloy parts can form or aluminium alloy is reprocessed to processing by improving the composition of aluminium alloy, to improve the case hardness of aluminium alloy.Now also have technology to realize by form surface abrasion resistance damage composite layer in aluminum alloy surface, but the existing technology such as processing, high-power electron beam radiation of generally melting by laser realize.Now also there is the method that adopts the organic solvent of carborundum particle to manufacture by agitating friction.
Can say, such manufacture method is fairly simple aborning, but still has weak point, is exactly in friction process, because the heat producing can not be distributed to the surface of alumina-base material uniformly, and occurs the uneven distribution problem of composite layer.
Summary of the invention
The object of the invention is, by the improvement to prior art scheme, to make the even thickness of aluminum matrix composite layer.
The present invention is achieved by the following technical solutions:
A kind of method for preparing surface aluminium based composite material, the molten slurry of organic solvent that is dispersed with 0.15-3.0 μ m carborundum particle and 0.25-0.35 μ m boron carbide particle is coated in to clean surface of aluminum plate equably, under the process conditions of 200-250 rev/min of friction stir welding machine velocity of rotation, horizontal speed of service 25-30 mm/min, aluminium sheet is carried out to surface stirring friction processing, and described organic solvent comprises alcohols, ketone, ethers; The weight ratio that described carborundum particle accounts for molten slurry is 25%-30%; The weight ratio that boron carbide particle accounts for molten slurry is 1%-3%; The temperature maintaining between aluminium sheet and friction stir welding machine surface is no more than 45 ℃.
Described organic solvent is selected from can ethanol, propane diols, acetone.
Described agitating friction processing need be carried out under dry air ambient.
Before described agitating friction processing, aluminium sheet will carry out cleaning-drying processing.
The invention has the beneficial effects as follows:
Technique of the present invention is simple, does not need superlaser or electron beam irradiation equipment, not only can cut down finished cost, and can not cause any pollution to environment.
