Description
Technical field
The present invention relates to field of compound material, in particular to a kind of using mullite and albite as the ceramics of constituent element
Enhance iron base composite material and preparation method thereof, machine components.
Background technique
Abrasion is one of main damage form of material, caused by economic loss it is quite surprising, every year because of attrition
Steel reached millions of tons.Ceramic material has the characteristics that high rigidity, high-melting-point, high chemical stability, opens up during being on active service
The excellent performances such as wear-resisting, heat-resisting, anti-corrosion are showed, can have been run steadily in the long term in bad working environments condition, reach metal material and be difficult to
The effect reached.But due to ceramic material poor toughness, do not have resistance plastic deformation and fatigue capability, and large-scale and complex-shaped
Forming parts it is difficult so that engineering ceramics is answering one to have been more limited in.
Ceramic material strengthening metal material has become the hot spot of research: CN101181741A uses industry Ti-Fe powder and B4C
Powder mixes green compact according to a certain percentage and is placed in casting as reactant, by forming Ti in metal from climing combustion reaction2B、
TiC ceramics enhance particle, achieve the purpose that reinforced metal.CN101195888A is by the above-mentioned same method of Ti, Cr, C powder
It is added in casting, has obtained (Ti, Cr) C, Cr7C3For the iron base composite material of ceramic strengthening phase.CN101214541A using Ni,
Ti and B4C briquetting preparation Ti2B, the manganese steel that TiC ceramic granule partial is strengthened.CN102366829A is using varigrained
Al2O3The surface strength and wearability for the steel that particle strengthening improves." high frequency melting prepares Al2O3Ceramic particle enhancing is heat-resisting iron-based
It is combined in composite material " (Ji Yuzhen, Bao Chonggao, foundry engieering, 2008,29 (7), 888~889.) using high-frequency heating melting
Negative pressure technology of infiltration casting is prepared for the Al for being suitable for using under high temperature friction and wear operating condition2O3Ceramics/heat-resisting iron-based surface layer composite wood
Material.And CN1800090A utilizes Al powder and Fe2O3From climing combustion react, be prepared for one layer in steel pipe inner wall and contain Al2O3Ceramics
Layer improves the wearability of steel pipe.
Above-mentioned patent of invention is substantially prepared for one layer of composite layer containing ceramic material in metal surface to strengthen
Metal material improves the overall performance of metal material.CN101181741A is preset in casting pattern may occur from
The briquetting of climing combustion reaction generates Ti by casting ignition reaction2B, TiC etc. forms hardening constituent on the surface of casting；
CN103436776A is by Cr3C2、Cr7C3Or Cr23C6Equal ceramic particles are placed in mold cavity, are distributed ceramic particle by casting
In the surface of workpiece, to achieve the purpose that surface peening, this method can not achieve the whole of material and strengthen；And in cast moulding film
Interior to occur to react from climing combustion, the reaction is not easy to control, easily leads to releasing bulk gas, and the hole that will lead to casting increases, and causes
Intensity decline.And CN102366829A and " high frequency melting preparation Al2O3Ceramic particle enhances heat-resisting iron base composite material " in casting
Add Al in surface2O3Particl method, it is therefore an objective to make Al2O3Particle dispersion is distributed in the matrix of steel, with strengthening metal material；But
Due to Al2O3There are problems that interface cohesion with steel, makes its strengthening effect that the purpose of anticipation be not achieved.In addition above-mentioned patent strengthens institute
The material used is Ti, Cr, B4The C or Al for providing mesh number2O3Powder, the higher cost of material.
In view of this, the present invention is specifically proposed.
