Abstract
The wear resistance material is formed by the processes of mixing iron powder, graphite, corundum powder (or short fibre) and inorganic Si-containing bonding agent, pressing and sintering under the protection of pure H2 or decomposed ammonia. It forms an intermediate phase between Al2O3 granules and the base body, its hardness lies between both of them. It improves the bond strength, thus improving the wear resistance and high temperature creep strength and features simple technological process and low cost.
Description
The invention belongs to a kind of manufacture method of iron base composite material, especially relate to the matrix material that a kind of particle (or staple fibre) strengthens iron-based.
Present particle (or staple fibre) strengthens the manufacture method of iron base composite material, is to adopt Al
2O
3Particle and stainless steel or high-speed steel-base mechanical compound.For example: Japanese Patent clear 62-238348 and document S.K.Mukherjee et al, Sintering of 434L Fe-rritic Stainless Steel Containing Al

2O
3Do not soak into base steel, only depend on particle dispersion in matrix, belong to a kind of mechanical type and coat, its binding ability is poor, is easy to come off.Thereby composite effect and wear resisting property are not good.In addition, Stainless Steel Powder and high speed comminuted steel shot cost an arm and a leg, the material cost height.
The wearing composite material that the purpose of this invention is to provide firm, the cheap and excellent property of a kind of combination.For finishing above-mentioned task, the technical solution adopted in the present invention is: reduced iron powder, graphite and corundum powder or staple fibre with industrial use are made raw material.
The reduced iron powder granularity of using is-80～-100 orders, and the granularity of lapis amiridis is less than 280 orders.Its proportioning is: lapis amiridis 3～15%Wt, graphite are 0.5～3%Wt, and all the other are reduced iron powder.
Add the mineral binder bond that contains Si, in shredder, mix and grind evenly, again press forming under 500～700MPa pressure.
Pressed compact is dried under 100～200 ℃ furnace temperature, again 1200～1500 ℃ with pure H2 or cracked ammonium protective atmosphere under sintering 40～180 minutes.Goods behind the sintering.Also can quench+temper technology, further improve hardness, tensile strength and the wear resistance of goods.
Because adopt above technical scheme, the present invention has following characteristics: adopt industrial reduced iron powder commonly used and lapis amiridis, its source is abundant, cheap.With powder metallurgic method preparation, technology is simple, and goods only need carry out precision work such as grinding or directly come into operation, and save material and the energy (with respect to the smelting method), and the composite effect of material is good, and wear resisting property is good; And can pass through Q-tempering technology, further improve its performance; The use range of material is wide, can be used for the manufacturing of normal domestic structural part, especially requires the production of attrition resistant workpiece.
Embodiment:
Raw material is prepared: lapis amiridis is worn into-320 orders, iron powder sieves-100 orders.
In grinding mixer, add graphite, the 0.5%wt of lapis amiridis, the 1%wt of 5%wt binding agent, all the other are iron powder, mixing grinds well.Mixed powder is poured in the pressing mold, behind press forming under 500～700MPa pressure, put in 100～200 ℃ of people's the stove and dry.Again at pure H
2Or sintering in the sintering oven of decomposition atmosphere protective atmosphere.The sintered heat insulating time is 40～180 minutes.
Goods behind the sintering can pass through quenching+tempering process, further improve its performance.
Its performance index can reach:
Relative density: 93～98%
Hardness: RRC56～65
Tensile strength: 450～520MPa
Wear resisting property: be 40 times of pure body material
Be 60
#20 times of steel (through quenching+low-temperaturetempering).
