Description
Technical field
The present invention relates to technical field of automobile, more particularly to a kind of sliding rail of automobile seat.
Background technology
Sliding rail of automobile seat is important in auto parts machinery one, and driver can be adjusted position according to personal custom
Put.The move mode of automotive seat is divided into manually and automatically electronic two kinds, and general superior automobile can use electronic slip, and usher to seat
Chair position memory function, after driver sits on operator seat and lights a fire, automotive seat meeting automatic sliding road predeterminated position, so that
Driver's steering position is comfortable.When the flame-out preparation of driver is got off, seat understands automatic sliding to rear, to facilitate driver to enter
Go out.
But in actual use, due to abrasion, foreign matter, get rusty, cause slide rail to slide difficult, so that seat is difficult to
It is mobile, bring very big inconvenience to life.
The content of the invention
It is an object of the invention to propose a kind of sliding rail of automobile seat and preparation method thereof, slide rail is enabled to carry lubrication
Function, non-corrosive, slide rail pivoting friction resistance is small.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of sliding rail of automobile seat, including two slide rails be arrangeding in parallel, are respectively equipped with lockable mechanism, and lead on two slide rails
Cross the unblock of same unlocking mechanism, the slide rail includes relative being slidably fitted to upper slide rail and glidepath together, it is described on
Slide rail section is in " n " shape, and its both sides side wall lower ends is outside and is folded upward at, and forms two outer walls, and the glidepath section is in " u "
Shape, its bottom wall is horizontally disposed with, and both sides Ce Bi tops are bent to form two inwalls still further below after bending inwards, the outer wall is embedded at down
Between the inwall and side wall of slide rail, be provided with rolling assembly between the outer wall and downslide trackside wall, the lockable mechanism include lock claw,
Lock claw support, bearing pin and torsion spring, torsion spring use the single-sided form, the upper slide rail and downslide track surface to have 20-30 μ m thicks
Plasma spraying Ni coats micron graphite and graphite ene coatings.
Sliding rail of automobile seat of the present invention, the plasma spraying Ni claddings that slide rail and downslide track surface have thereon are micro-
Meter Shi Mo and graphite ene coatings, are prepared via a method which to obtain：
Coating of the present invention is that Ni cladding micron graphites are mixed with graphite ene coatings.Preferably, the weight ratio
It is (3-5):1, preferably 4:1.
The mixing is that coating is dusted using planetary ball mill and centrifugal spraying granulator.Its technique includes：
(1) by Ni cladding micron graphite particles and Graphene ball milling at least 5 minutes on planetary ball mill；
(2) when ball milling stops first 5 minutes, organic binder ball milling is added, obtains suspension；
(3) suspension is carried out into mist projection granulating, obtains Ni cladding micron graphites and Graphene agglomerated particle.
The Ni is coated micron graphite and is sprayed on slide rail with Graphene agglomerated particle by the present invention by plasma spraying.
The plasma spraying, its electric current is 400-700A, and voltage is 30-70V, main gas argon flow amount 50-140L/min, powder feed rate
25-60g/min.Preferably, electric current is 550A, voltage 30V, argon flow amount 50L/min.
Ni of the present invention coats micron graphite particle, is existing product, and those skilled in the art can be by market
It is commercially available, it is also possible to which the method according to prior art is prepared.The present invention is no longer limited with regard to it.
Coating of the invention, in process of friction and wear, graphite is constantly separated out from nickel bag graphite particle, in tangential masterpiece
Lower flowing is used, the effect of filling and leading up can be played to ditch dug with a plow, thus the wearability of main shaft can be improved.And the Graphene for adding, it is more suitable
It is sliding, main shaft surface is attached to, reduce its frictional resistance.
Composite coating thickness of the invention is about 20-30 μm, and its hardness is significantly improved compared with matrix and nickel coating, is exceeded
500HV0.2.Meanwhile, addition Graphene causes that crystal grain is refined in composite deposite, 40nm of the average grain size from pure Ni
Drop to 20nm or so.
Composite deposite of the invention causes that coefficient of friction and wear rate are reduced simultaneously, with relatively low coefficient of friction, while
With the wearability more excellent than Cr coating.Under each load, wear rate is than matrix reduction by more than 50%.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
Embodiment 1
A kind of sliding rail of automobile seat, including two slide rails be arrangeding in parallel, are respectively equipped with lockable mechanism, and lead on two slide rails
Cross the unblock of same unlocking mechanism, the slide rail includes relative being slidably fitted to upper slide rail and glidepath together, it is described on
Slide rail section is in " n " shape, and its both sides side wall lower ends is outside and is folded upward at, and forms two outer walls, and the glidepath section is in " u "
Shape, its bottom wall is horizontally disposed with, and both sides Ce Bi tops are bent to form two inwalls still further below after bending inwards, the outer wall is embedded at down
Between the inwall and side wall of slide rail, be provided with rolling assembly between the outer wall and downslide trackside wall, the lockable mechanism include lock claw,
Lock claw support, bearing pin and torsion spring, torsion spring use single-sided form, the upper slide rail and downslide track surface have the grade of 20 μ m thicks from
Son spraying Ni cladding micron graphites and graphite ene coatings.
Plasma spraying Ni cladding micron graphites and graphite ene coatings that described slide rail surface has, by the following method
Prepare：
Coating material is dusted using planetary ball mill and centrifugal spraying granulator.Its technique includes：
(1) by Ni cladding micron graphite particles and Graphene ball milling at least 5 minutes on planetary ball mill；
(2) when ball milling stops first 5 minutes, organic binder ball milling is added, obtains suspension；
(3) suspension is carried out into mist projection granulating, obtains Ni cladding micron graphites and Graphene agglomerated particle.
The Ni is coated to slide rail by micron graphite and Graphene coating spraying by plasma spraying.The plasma
Spraying, its electric current is 550A, voltage 30V, argon flow amount 50L/min.
The composite coating of embodiment 1 causes that coefficient of friction and wear rate are reduced simultaneously, with relatively low coefficient of friction, while
