Abstract
The formula of tin bronze based self-lubricating composite material comprises (wt%) 80-93% of tin bronze, 1-6% of nickel, 0.40-4% of aluminium, 0.2-1.8% of aluminium oxide, 1.2-7.0% of graphite and the rest is lead oxide, and it is made up by adopting cold-pressing forming process of powder metallurgy technology and free sintering process, and can be used at room temp. -450 deg.C, middle-low speed and middle-low load condition.
Description
The present invention has narrated a kind of tin-bronze base self-lubricating composite material and preparation method thereof.
The tinbronze material that casting or powder metallurgy are made, high temperature resistant, anti-oxidant and corrosion-resistant etc. because of it has good physics, mechanical property, be the important physical construction material of a class.But because the slide unit of its making, as bearing, bearing shell and lining etc., under conditions such as oil-free lubricatoin and high temperature, sliding-frictional resistance is big, temperature rise, and wearing and tearing are violent, even seize is stuck etc.Therefore, at Aeronautics and Astronautics, weapons system and civilian machinery as at the spot contact bearing retainer of 300 ℃ of uses with at the employed slide units such as sliding surface bearing of the plasterboard dryer of 250～300 ℃ of uses, when just requiring not outer apply oil, still have good physics, mechanical property during in room temperature～450 ℃, low frictional coefficient and characteristic such as wear-resistant.
The purpose of this invention is to provide a kind of tin-bronze base self-lubricating composite material that can under room temperature～450 ℃, middle low speed, middle-low load condition, use and preparation method thereof.
Content of the present invention:
On prescription, the present invention selects the matrix of tinbronze as this material for use, and nickel is mutually wear-resisting with aluminum oxide, and aluminium is the hydrotropy phase, constitutes the main composition of this material.And adding suitable amount of graphite and oxide compound.Rely on tinbronze-nickel-aluminium to guarantee the mechanical property of this material.Aluminum oxide strengthens wear resistance.Graphite and plumbous oxide guarantee the oilness of this material in room temperature～450 ℃.Thereby realize the purpose of self-lubricating.
Concrete prescription of the present invention (weight percentage) is: tinbronze 80～93%, and nickel 1～6%, aluminium 0.40～4%, aluminum oxide 0.2～1.8%, graphite 1.2～7.0%, surplus is a plumbous oxide.
The granularity requirements of each component of the present invention is: tinbronze 76 μ m, nickel 76 μ m, aluminium 76 μ m, aluminum oxide 76 μ m, graphite 76 μ m, plumbous oxide 38 μ m.
Screening formulation of the present invention (weight percentage) is: tinbronze 86～92%, and nickel 3～6%, aluminium 0.4-1%, aluminum oxide 0.4-1%, graphite 4～7%, surplus is a plumbous oxide.
On technology, the present invention adopts powder metallurgical technique coldmoulding and free sintering process to make blank, is practical product after mechanical workout.Characteristics such as oil length height when the room temperature of prepared～450 a ℃ tin-bronze base self-lubricating composite material has high strength, low friction, wear-resistant, immersion oil thus, homogeneity are good.Preparation process of the present invention is: after tinbronze, nickel, aluminium, aluminum oxide, graphite and lead oxide powder are mixed by a certain percentage; the coldmoulding in the punching block of packing into; place the free sintering oven of hydrogen shield; be warming up to 700-1000 ℃; be incubated 15～60 minutes; freely be cooled to room temperature, can make the blank of this material.Typical physical, mechanical property and the friction and wear characteristic of the tin-bronze base self-lubricating composite material that makes by above-mentioned prescription and technology such as table 1, table 2 are listed.
