Domain.
Background technology
With the increase year after year of city automobile recoverable amount, congestion in road situation is serious all the more, due to motor vehicle exhaust emission
Caused environmental quality issues is also increasingly valued by people.In some cities, or even suggest that driver hands in waiting
When logical lamp is surpassed after one minute, engine is closed as far as possible, to reduce the discharge of harmful substance.At the same time, French PSA company Zeng Yan
Study carefully and show, vehicle idling, which is shut down, can reduce the % of its fuel consumption per hundred kilometers 2.5 % ~ 10.Thus, in economical and environmentally friendly dual interests
Driving under, engine automatic start-stop technology has gradually come into the visual field of people.
Engine automatic start-stop technology can be described as popularizing most fast, one of development automobile environment-protection technology the swiftest and the most violent in recent years,
Its extensive use brings more economy to the people that vehicle is driven in crowded cities.However, start stop mode engine
Frequently restart caused lubrication problem, increasingly paid close attention to by vehicle manufacturer, traditional antifriction alloy layer has been difficult
Meet more complicated duty requirements, friction environment is having oil film and the intermembranous frequent transitions of oil-free, accelerates the abrasion of anti-attrition layer
And be allowed to fail, cause bearing shell service life seriously to reduce.
In recent years, each bearing shell manufacturer forms abrasion reducing polymer coating by spraying coating process in bearing shell working surface, to substitute
Traditional antifriction alloy layer, in these techniques, more options molybdenum disulfide or graphite are used as lubrication phase, and according to different preparations
Technique, different materials proportioning obtain the bearing shell polymer coating of excellent performance.It is more detailed through retrieval, the A of patent CN 104879385
Disclose a kind of coating and its spraying coating process containing molybdenum disulfide, its performance is in the painting using molybdenum disulfide as kollag
It is more prominent in layer, but do not improve significantly, and pre-treating technology is relatively complicated, the U of patent CN 203979145 disclose one
Bearing shell of the kind with black composite coating, the black composite coating possess more excellent performance relative to multi-elements alloying coating, but
Its surface roughness is larger, is easily caused coating surface discontinuity, and then accelerates abrasion, reduces the service life of bearing shell.
The content of the invention
It is an object of the invention to provide a kind of bearing shell polymer coating and its preparation technology, and it on bearing shell base material by applying
One layer of articulamentum is covered, the bond strength of outer layer lubricant coating is substantially improved, while reduces lubricant coating surface roughness, by adding
Enter fluorographite and optimize material mixture ratio and preparation technology so that coating has more preferable wearability and anti-attrition, extends bearing shell
Service life.
The technical proposal of the invention is realized in this way：A kind of bearing shell polymer coating, it is characterised in that：The surface of bearing shell
Cover internal layer articulamentum, the surface covering outer layer lubricating layer of internal layer articulamentum；
Its specific preparation technology, comprises the following steps：

Cerium fluoride 1 ~ 5% is put into low speed ball milling 12 hours in ball mill, is then added to uniform stirring in solution, and add before spraying
Enter coupling agent 0.1 ~ 3%, surplus is dispersant, the mixed slurry of acquisition is sprayed at into bearing shell surface, coating thickness forms coating
Internal layer articulamentum.
（3）Secondary spraying outer layer lubricating layer：By mass by polyamidoimide 5 ~ 12%, graphite 10 ~ 20%, fluorination
Graphite 5 ~ 10%, surplus are that dispersant is sufficiently mixed uniformly and is sprayed on internal layer, form the outer layer lubricating layer of coating.
（4）Hot setting processing：Bearing shell after secondary spraying is placed at aeration-drying 30 ~ 60 minutes, then placed
Processing 1 hour is further dried in 150 DEG C of baking ovens, is finally putting into Muffle furnace and carries out hot setting 1.5 hours, it is empty after taking-up
It is cooled to room temperature.
The sand particle diameter that described blasting treatment uses is not less than 80 mesh.
Described graphite and fluorographite is powder, and particle diameter is less than 10 microns, and both add mass ratio as 2:1.
Described dispersant is any one in dimethylformamide, dimethyl acetamide, 1-METHYLPYRROLIDONE or two
Kind, wherein any two kinds of ratio is volume ratio 1:1.

The positive effect of the present invention is that fluorographite is a kind of compound between graphite layers of prepared by carbon and fluorine directly react,
When fluorine carbon ratio is not less than 1, fluorographite has preferable chemical stability and weatherability, and it is under high temperature, vacuum, high load capacity
There is more superior greasy property compared to molybdenum disulfide and graphite.Fluorographite and graphite are fabricated to coating according to a certain ratio
Stable outer layer, on the premise of coating integrity energy is ensured, obtain preferably chemically and thermally stability so that coating entirety exists
Under various harsh conditions, in the unstable operation environment that especially frequent start-stop is formed, good greasy property is remained,
When the mass ratio of graphite and fluorographite is 2:When 1, the coating performance of acquisition is best.By carborundum, iron oxide, six sides nitridation
The structure enhancing phase and stable phase of boron, cerous fluoride, titanium dioxide as internal layer articulamentum, be further ensured that coating uses the longevity
Life.
In bearing shell surface pretreatment process to be sprayed, in order to reduce operational sequence, bearing shell surface to be sprayed is using directly spray
Sand processing, while degreasing, forms uniform roughness on surface to be sprayed, is then cleaned by ultrasonic with grease removal agent,
Make surface thoroughly clean, ensure that coating internal layer can preferably be attached to metal base.
