Abstract
A metal ceramic surface composite material and a production process thereof belong to a metal matrix composite material and a production process thereof. The invention solves the problem that the surface of a metal matrix is compounded with ceramic by using a common casting method and is formed into a product in one step. The production process of the invention comprises the following steps: crushing the ceramic material into particles, proportionally and sequentially adding and mixing the components, preheating a sand mold, spraying the mixed slurry to the surface of the sand mold for foaming, closing the mold and standing, and melting and casting the metal matrix for molding. The invention simplifies the production process, can obtain a final product by one-step molding, can improve the performances of wear resistance, heat resistance and the like of the metal surface, and saves materials. The invention is used for producing ferrous and nonferrous metal surfaces and composite materials.
Description
The invention belongs to metal-base composites and production technology thereof.Closely-related with it at present technology is to adopt casting die (Songyuan City is great beautiful, " manufacture method of the dispersion-strengthened type composite of particle ", Japan Patent JP59-145742) to produce the aluminum matrix composite that ceramic particle strengthens.The technical process of this method is at first ceramic powders to be made the formed body of porous, puts into the casting mold casting metals equably, makes metal liquid immerse the formed body of porous by the atmospheric pressure of 500-1000 subsequently.Be rolled again after solidifying or push, make porous, shaped fragmentation body be graininess and be dispersed among the metal, thereby obtain the aluminum matrix composite that whole compound ceramic particle strengthens.This method needs pressurization in recombination process, also need rolling or extruding after compound, and raw material need be reprocessed just can become final products, so complex technical process.
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of metal ceramic surface composite and production technology thereof are proposed, compound and products thereof being molded in the casting process of setting of metal and pottery once finished, pressurization and following process process have been saved, directly obtaining inside is metallic matrix, the top layer is the product of metal ceramic composite bed, can improve the metal surface wear-resistingly, anti-wash away, heat resistance, saving metal material.
In order to realize the foregoing invention purpose, technical scheme of the present invention is: batch mixing at first, simultaneously with the sand mold preheating, then with the slurry spary that mixes to the sand mold surface blister, mould assembling was left standstill after foaming was handled, and simultaneously with metal molten, used the cast molding of normal pressure conventional cast method then.
The used raw material of the present invention are made up of intermixture, inorganic adhesive, organic adhesive, blowing agent, reinforcing agent, metal matrix material.Wherein adopt water as intermixture, ratio is 10-60%wt, in boric acid, the Boratex any is as inorganic binder, ratio is 1-10%wt, adopt in industrial syrup, phenolic resins, epoxy resin, the methyl fibre resin any as organic binder bond, ratio is 1-10%wt: adopt sodium alkyl sulfonate or alkyl sulfonic acid potassium or urethane fat as blowing agent, ratio is 1-10%wt; Select industrial SiO for use
2, Al
2O
3, MgO, SiC, Si
3N
4, AlN and ZrO
2In any ceramic powders do reinforcing agent, ratio is 30-80%wt.Metal matrix material adopts cast iron or cast steel or Birmasil or cast copper alloy.
In material therefor, above-mentioned every kind of ceramic material all is ground into the powder of granularity 0.01～1mm, and sodium alkyl sulfonate or alkyl sulfonic acid potassium or urethane fat are the aqueous solution of commercially available 20-80%wt; The industry syrup is industry proportion 2-4g/cm
2Liquid.Other various material purity are 90%-99.99%.
Batch mixing is undertaken by the agitator that motor is bought with 500-2000 rev/min speed drive in agitator.Charging sequence is followed successively by intermixture, inorganic binder, organic binder bond, blowing agent and reinforcing agent, every kind of material adds the back stirring and was added into down a kind of material in 5～10 minutes again, is suspended state (the agitator bottom does not have precipitation) until last ceramic powders in mixed liquor.
The sand mold preheating was carried out 6～14 hours at 80 ℃～200 ℃.
Surperficial spary foaming to the casting sand type after the preheating.The spary foaming is by the nozzle on the agitator, is (1～10) kilogram/mm with pressure
2Compressed air, with (1～5) kilogram/minute flow with the slurry spary that the mixes casting sand type surface after the preheating, by the effect of organic burning volatilization and blowing agent, form the thick porous ceramic layer of 2-8mm on the surface, loam core.Hole in the porous ceramic layer should evenly distribute, and mutual UNICOM, and the bore hole size size should be controlled between the 0.5-2mm.
The surface of final products of the present invention is a ceramic-metal composite, and matrix is a metal, and this metal is non-ferrous metal or its alloy, ferrous metal or its alloy.Do not have separating interface between composite bed and the matrix, metal by matrix to surperficial continuous transition.Ceramic particle evenly distributes in the composite bed, and content is 10%～70%wt.
The present invention compares with background technology and has the following advantages:
(1), the surface infiltration combination process that proposes of the present invention makes metal compound in the metal surface with pottery, and is rather than whole compound.At metal surface (as Fig. 2), because the invigoration effect of ceramic particle, wear-resisting, anti-the washing away with performance such as heat-resisting that makes the metal surface improved.Therefore, for the occasion of only requiring the material surface performance, can save metal material greatly.
(2), the present invention adopts normal pressure conventional cast method to realize the compound of metal and pottery, avoided the pressurization in other method to wait other complex techniques process, simplified production process.
(3), metal and compound and moulding product of pottery are once finished, directly obtain to have the final products of the various sizes of metal ceramic composite bed, and no longer carry out following process and directly use by the conventional cast method.And adopt other method, after metal and the Ceramic Composite, often need following process to use.
