Abstract
The invention discloses a sliding rail for an automobile sliding door. The surface of the sliding rail is provided with a Ni wrapped micrometer graphite and graphene coating with the thickness being 20-30 micrometers, and the Ni wrapped micrometer graphite and graphene coating is sprayed through plasma. By means of the coating, the friction coefficient and the abrasion rate are reduced at the same time, and the sliding rail has a relatively low friction coefficient and meanwhile has excellent abrasion resistance. At various loads, the abrasion rate is reduced by 50% or above compared with a base body.
Description
Technical field
The present invention relates to technical field of automobile, more particularly to a kind of sliding door of motor vehicle slide rail.
Background technology
Automobile, particularly multi-functional automobile, such as MPV or commercial vehicle, its tail gate are manually or electronic
Open.External pulling type of its opening ways different from orthodox car, but slide anteroposterior.Described slip relies on upper and lower installed in car door
The slide mechanism of both sides, usually guide rail coordinate lockable mechanism, realize the slide anteroposterior of car door, have reached and have saved opening and closing space
Purpose.
101169026 B of CN disclose a kind of sliding door structure of automobile, and which is utilized door main body to vehicle fore-and-aft direction
At least one guiding mechanism of guiding, makes door main body be opened and closed in vehicle front and back upward sliding relative to car body peristome,
Characterized in that, aforementioned guiding mechanism has：Guide rail, which is configured on door main body along vehicle fore-and-aft direction；And arm, which is in the past
State the vehicle fore-and-aft direction of car body peristome door opening direction side edge protrusion, engage with aforementioned guide rail and along vehicle width
The link that falls down to the ground freely is acted in direction, starts the initial stage in door main body, by the door main body on the outside of the vehicle-width direction of body panel
Release, on aforementioned arm arrange arm side holding section, the arm side holding section using aforementioned arm by door main body to vehicle-width direction
When outside is released, engage with the car body side holding section at the edge of the aforementioned door opening direction side for being located at car body peristome and keep
Door main body, after aforementioned vehicle body side holding section is engaged with arm side holding section, allows aforementioned door main body to beat to door relative to arm
Evolution is to Slideslip.
Although sliding door of motor vehicle is various, the slide rail of upper and lower 2 balances is all fixed mostly on car body to draw
Lead and accommodate car door to move forward and backward.As the slide rail exposes, sliding friction, and ingress of air can be produced in use
In Acid-base Gas, or even rain penetration, the pollutant such as the mud that more even automobile has fallen.Therefore in actual use,
Due to abrasion, foreign body, get rusty, cause slide rail to slide difficult, so as to be difficult to stretch, very big inconvenience is brought to life.
The content of the invention
It is an object of the invention to propose a kind of sliding door of motor vehicle slide rail and preparation method thereof, enable to slide rail and carry
Lubricating function, non-corrosive, slide rail pivoting friction resistance are little.
It is that, up to this purpose, the present invention is employed the following technical solutions：
A kind of sliding door of motor vehicle slide rail, the slide rail surface have the plasma spray Ni cladding microns of 20-30 μ m thicks
Graphite and graphite ene coatings.
Sliding door of motor vehicle slide rail of the present invention, is prior art, its design with manufacturer and it is different.This
The bright contribution for prior art is more the coating, those skilled in the art can according to specific Automobile Design with
And technological requirement, voluntarily determine the structure and composition composition of sliding door of motor vehicle slide rail.
Plasma spray Ni cladding micron graphites and graphite ene coatings that slide rail surface of the present invention has, by as follows
Method is prepared：
Coating of the present invention is that Ni cladding micron graphites are mixed with graphite ene coatings.Preferably, the weight ratio
For (3-5):1, preferably 4:1.
The mixing is coating to be dusted using planetary ball mill and centrifugal spraying granulator.Its technique includes：
(1) by Ni cladding micron graphite granules 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, suspension is obtained；
(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 Graphene coating spraying on slide rail by plasma spraying by the present invention.It is described
Plasma spraying, its electric current are 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 granule, is existing product, and those skilled in the art can pass through 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 which.
The coating of the present invention, in process of friction and wear, graphite is constantly separated out from nickel bag graphite granule, 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, its frictional resistance is reduced.
About 20-30 μm of the thickness of multiple plating of the present invention, its hardness is significantly improved compared with matrix, more than 500HV0.2.Together
When, adding Graphene in the coating and crystal grain is refined, average grain size drops to 20nm or so.
The composite deposite of the present invention causes coefficient of friction and wear rate while reducing, with relatively low coefficient of friction, while
With the wearability more excellent than Cr coating, and due to chromium plating, can effective antirust, which realizes two kinds of antirust and antifriction simultaneously
Function.Under each load, wear rate reduces by more than 50% than matrix.
Specific embodiment
Technical scheme is further illustrated below by specific embodiment.
Embodiment 1
A kind of sliding door of motor vehicle slide rail, the slide rail surface have the plasma spraying Ni cladding micron stones of 20 μ m thicks
Ink 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 granules 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, suspension is obtained；
(3) suspension is carried out into mist projection granulating, obtains Ni cladding micron graphites and Graphene agglomerated particle.
