Sliding characteristic.The high molecular material for being used in space lubricants is mainly polytetrafluoroethylene (PTFE), polyimides, phenolic resin, asphalt mixtures modified by epoxy resin
Rouge etc. the advantages of high molecular material is that friction and wear behavior is not influenced by atmosphere compared with other solid lubricants,
The tribological property of PTFE in a vacuum is enough to illustrate this feature.

Summary of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, providing, a kind of coefficient of friction is low, abrasion loss is few, anti-
The space solid lubricant coating and preparation method thereof that radiation property is good, structure is uniform, continuous, thickness is about 20 μm.This method section
It learns, rationally, achievements conversion potentiality are big, and practical value is wide, are mainly used on spacecraft lubrication device.
The purpose of the present invention is adopt the following technical solutions realization.A kind of radiation resistance space solid lubricant coating and preparation
Method, solid lubricant coating composition be PTFE particle, mass ratio be 80-90 part, size be 40-100 mesh, carbon fiber particles,
Mass ratio is 10-20 parts, and size is 100-200 mesh, and solid lubricant coefficient of friction low (0.132~0.192), abrasion loss are few
(1mg~15mg), Flouride-resistani acid phesphatase is good, structure is uniform, continuous, thickness is about 20 μm, and preparation method mainly includes that sample prepares, throws
Light processing, PTFE and carbon fiber particles screening, depositing coating, surface wipes, the test of vacuum tribological property, abrasive dust collect step
Suddenly.Wherein in vacuum tribological property testing procedure, vacuum degree is about 10 in testing machine vacuum chamber-2MPa-10-7MPa, load
For 4N-12N, speed 0.2m/s-2.4m/s, frictional distance 1000m, dual face material is standard rolling bearing steel ball (GCr15),
Having a size of Φ 10mm, hardness HRC66.6.
The Analysis on Mechanism of carbon fiber filling PTFE Coatings in Vacuum tribological property.
The factor for influencing carbon fiber filling PTFE coating tribologic performance is more, mainly there is environment, load, speed, contact
Mode, surface roughness etc..Under the conditions of vacuum environment, the main shadow loaded and speed of PTFE coating tribologic performance
It rings, does not change as factors such as environment, the way of contact and surface roughnesses.At the initial stage of entire friction process, friction
The way of contact is point-face formula, and coating material surface has certain surface roughness, based on abrasive wear, has ditch dug with a plow effect
It answers, coefficient of friction increases rapidly at friction initial stage.With the progress of friction, PTFE enters plastic deformation, adhesion and material and turns
Shifting state causes coefficient of friction to be continuously increased.The surface of PTFE coating material forms self-lubricating film, plays solid lubricant
Effect, such two kinds of materials enter stable friction phase earlier, and coefficient of friction with sliding distance increase no longer
It changes.Therefore the friction coefficient speed, the variation tendency of load of PTFE coating material in a vacuum are almost the same.
The symmetrical structure of PTFE makes strand have greater stiffness, and the abrasive dust of friction surface richness product is difficult to be embedded in matrix again
In.At a lower rate, coating material abrasion after, friction surface richness product abrasive dust play the role of solid lubricant with
The increase of speed, this lubricant enhancing, thus reduce abrasion loss.
At the initial stage of friction, since the surface of two kinds of materials all has certain surface roughness, PTFE coating material with
The way of contact of GCr15 steel is point-face formula again, and PTFE coating material surface forms lubricating film again in friction process.So mill
Damage amount reduces with the increase of speed.As the carry out way of contact of friction is converted into surface-to-surface formula by point-face formula.Identical
Abrasive conditions under, with the raising of speed, shear force value suffered by PTFE coating material surface is increased accordingly, what abrasive dust fell off
Probability increases, the wear resistance decrease of material, meanwhile, with the increase of speed, PTFE coating material wear surface was being worn
The frictional heat gathered in journey increases, and PTFE coating material is gradually turned to viscosity flow state from the glassy state under low temperature condition
Become, the softening degree of PTFE coating material performance is gradually increased, and the Large molecule active of polymer P TFE matrix increases, and makes polishing scratch table
The probability that " step " pattern in face falls off increases, and abrasive dust increases, and abrasion loss also increases with it.
It is viscoelastic material that influence of the load to PTFE coating material frictional behaviour, which is mainly manifested in PTFE coating material,
Viscoelastic deformation occurs under external force for PTFE.
On the one hand, as load further increases, the frictional heat generated in wear process increases, PTFE coating material table
The viscoplasticity degree revealed increases, and PTFE coating material macromolecule inter-chain entanglement starts to release strongly, and high polymer PTFE enters viscous
Fluidised form, macromolecular chain integrally participate in moving, and melting phenomenon occurs in surface, and polymer surfaces molecular activity greatly increases.Meanwhile with
Frictional heat generation, friction surface temperature raising causes the crystallinity of polishing scratch adjacent material to reduce, cause increase abrasion loss.
In spacecraft running track environment, there are a large amount of miscellaneous radiation, such as: alpha ray, β ray, γ are penetrated
Line, neutron ray and elemental oxygen etc..These radiation can cause irradiation reaction to coating surface, make coated surface material radiation drop
Solution is reacted with crosslinking with radiation, and material molecule amount substantially reduces, and abrasion loss increases in friction process.Carbon fiber fills PTFE coating
When, carbon fiber itself has good lubricity, plays a supporting role simultaneously, enhances the associativity of PTFE coating and matrix, subtracts
Abrasion loss in few friction process.
The invention has the following advantages that
1, solid lubricant coefficient of friction is low, abrasion loss is few, Flouride-resistani acid phesphatase is good；
2, solid lubricant thickness is about 20 μm, and structure uniformly, continuously, is mainly used on spacecraft lubrication device；
3, solid lubricant preparation method is scientific, reasonable, and achievements conversion potentiality are big, and practical value is wide.
