Abstract
The present invention relates to high-temperature corrosion resistances and self-lubricating field, and in particular to a kind of metal-based self-lubricating composite material of fire-resistant oxidation resistant and preparation method thereof.The composite material is using high alumina nickel-base alloy as matrix, calcirm-fluoride/barium fluoride eutectic and enamel are self-lubricating phase, using aluminum oxide as hard phase, is collectively constituted using the rare earth oxide that ceria, yttria etc. arbitrarily match as antioxidant, be prepared through discharge plasma sintering.Wherein, according to weight percent, high alumina nickel-base alloy is 65%~82%, and self-lubricating phase is 8%~15% (wherein calcirm-fluoride/barium fluoride eutectic≤10%, enamel are 3~10%), and aluminum oxide is 6~15%, and antioxidant is 2~10%.High alumina design, the addition of antioxidant and new type high temperature self-lubricating phase enamel that the present invention passes through nickel-base alloy, so that the composite material has been had both high temperature resistant, anti-oxidant and excellent self-lubricating comprehensive performance, can be used for the production of components under anti-oxidant, high temperature resistant, self-lubricating environment.
Description
Technical field:
The present invention relates to high-temperature corrosion resistances and self-lubricating field, and in particular to a kind of Metal Substrate of fire-resistant oxidation resistant is from moistening
Sliding composite material and preparation method, the composite material can be used for the life of components under anti-oxidant, high temperature resistant, self-lubricating environment
It produces.
Background technique:
Fretting wear and lubrication state under the harshness working condition such as high temperature, high speed and top load are to determine aeroplane engine
One of thrust ratio and the key factor of service life of the space mechanisms systems such as machine, space vehicles tool, spacecraft.In high temperature item
The many equipment and components to work under part require that Tribological Systems still have good lubricating status under thermal extremes,
Such as: the operating temperature for being insulated diesel engine is up to 760 DEG C, and the lubrication of cylinder sleeve and piston ring and valve lever is particularly important.
Cylinder sleeve and the lubricating method of piston ring sliding contact are the bottom ends (bottom end temperature is lower) that piston ring is placed on to piston at present, are made
Phase MoS is lubricated with common low-temperature solid2The target of self-lubricating solid, but piston ring and piston in the structure are realized with PTEE
Annular space between top reduces the whole efficiency 5~10% of engine, it is therefore desirable to be moistened using the higher solid of heat resistance
Sliding material.And in turbine aircraft engines, the operating temperature of bearing and lubrication phase also reaches 650 DEG C, partial joint bearing
Service temperature be even more reach 900 DEG C even more than, slide unit sealing and the lubrication in thrust disc mutually must satisfy high temperature resistant,
High-strength needs.In addition, engine bushing is easy to appear fretting wear and fracture under high temperature and high speed operating condition, use is resistance to
High temperature solid self-lubricants composite material can reduce the fretting wear of bushing or oscillating bearing under hot conditions.
In order to meet high temperature resistant, high-mechanic and the impact flexibility requirement of solid self-lubricating composite material, generally use resistance to
Matrix of the thermalloy as composite material.While fretting wear high temperature oxygen occurs for the heat-resisting alloys such as Ni-based, cobalt-based, iron-based
Change, generates a kind of hard and smooth compacting oxide skin(coating), also known as adamantine layer in wear surface.Adamantine layer have glass appearance and
Polycrystalline feature can be effectively reduced resistance of taxing (reducing coefficient of friction), protect matrix, prevent frictionally damage.The shape of adamantine layer
At process include the oxidation of alloy, the formation of oxide abrasive grain, abrasive grain rubbing surface roll and polycrystallization, glazing.Currently,
Self-lubricating phase in high temperature self-lubricating composite material generallys use fluoride (such as: the eutectic object of calcirm-fluoride and barium fluoride), nitridation
Boron etc..The self-lubricating property of high temperature self-lubricating composite material (at especially 800 DEG C of service temperature high temperature) is very dependent on from profit
The mutually excellent high temperature oxidation resistance of alloy in the high-temperature stable and composite material of sliding phase.In process of friction and wear, composite material
The effect of self-lubricating film layer that surface is formed must have both self-lubricating and resistance to high temperature oxidation simultaneously.And under actual condition, by common
Oxide adamantine layer and the film layer that collectively constitutes of fluoride, the dual function of self-lubricating and resistance to high temperature oxidation can not be had both completely
Energy.The formation period of adamantine layer changes with the variation of alloying component and friction temperature.Before adamantine layer formation, alloy
Coefficient of friction it is very high, abrasion loss is big.After once adamantine layer is formed, since corrosive media (such as: oxygen, sulfide) is in fluorine
Diffusion velocity in compound, adamantine layer is fast, and with the lasting progress of high-temperature oxydation, oxide abrasive grain increases, and adamantine layer constantly increases
Thickness is until rupture.At this point, the frictionally damage of composite material will become once again seriously.
According to China's national defense construction and industrial development to the service demand of high temperature moving component, need to develop a kind of resistance to height
The oxidation resistant novel metal based self lubricated composite material of temperature can be on active service, the movement portion of high-mechanic with preparation in 800 DEG C of temperatures above
