Abstract
The invention discloses a self-lubricating slide rail, which has a plasma sprayedCr3C2-NiCi- graphene coating in thickness of20-30Mum. The composite coating of the present invention simultaneously reduces the coefficient of friction and wear rate, with lower coefficient of friction, and better wear resistance than the Cr coating. Under each load, it reduces the wear rate by more than 50%.
Description
Technical field
The present invention relates to extensible member technical field, more particularly, to a kind of self-lubricating slide rail and preparation method thereof.
Background technology
Slide rail also known as on guide rail, slideway, the cabinet that refers to be fixed on furniture, drawer for furniture or cabinet plate discrepancy activity
Five metals connection member, slide rail is applied to the wooden drawer with furniture such as steel drawers such as cabinet, furniture, official document cabinet, bathroom cabinet even
Connect.
Inside the slide rail that naked eyes cannot be seen, it is its bearing arrangement, this part is directly connected to its load-bearing energy
Power.Existing ball guide in the market, roller bearing slide rail, also there is silicon wheel slide rail., by the rolling of steel ball, exclusion automatically is slided for the former
Dust on rail and foul, thus ensureing the cleaning of slide rail, will not affect its sliding function because foul enters internal.Steel simultaneously
Pearl can make active force to surrounding diffusion it is ensured that drawer stability both horizontally and vertically.Silicon wheel slide rail life-time service,
The chip producing in friction process is in snowflake shape, and its band can also be got up by rolling, does not equally interfere with drawer
Slide freely.
But in actual use, due to abrasion, foreign body, getting rusty, leading to slide rail to slide difficult, thus being difficult to stretch
Contracting, brings very big inconvenience to life.
Content of the invention
It is an object of the invention to proposing a kind of self-lubricating slide rail and preparation method thereof, enabling to slide rail and carrying lubrication work(
Can, non-corrosive, slide rail pivoting friction resistance is little.

Body supporting part, connecting portion, described fixed part is fixed on described drawer incorporating section；It is empty that described ball support portion is located at described storage
Between internal, support described rolling element；Described connecting portion, one end is connected to described ball support portion, and the other end passes through described evolution
Face leads to the outside of described accommodation space, is connected to described fixed part, and described connecting portion forms 50 with respect to described fixed part
Spend the angle in the range of 70 degree, described slide rail surface has the plasma spraying cr of 20-30 μ m thick3c2- nicr- Graphene applies
Layer.
The plasma spraying cr that slide rail surface of the present invention has3c2- nicr- graphite ene coatings, by the following method
Prepare:
Cr of the present invention3c2- nicr- Graphene is cr3c2With nicr and Graphene as a component according to weight
Than (5～3): (2～1): 1 mixes.Preferably, described weight is than for 4:1:1.
Described mixing is using planetary ball mill and centrifugal spraying granulator, coating to be dusted.Its technique includes:
(1) by cr3c2With nicr, not reprecipitation is milled on planetary ball mill；
(2) Graphene is added to continue ball milling at least 10 minutes；
(3), when ball milling stops first 5 minutes, add organic binder ball milling, obtain suspension；
(4) suspension is carried out mist projection granulating, obtain cr3c2- nicr- Graphene agglomerated particle.
The present invention passes through plasma spraying by described cr3c2- nicr- Graphene agglomerated particle sprays on slide rail.Described etc.
Plasma spray, 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.
The composite coating thickness of the present invention is about 20-30 μm, and its hardness significantly improves, more than 500hv compared with matrix0.2.With
When, composite coating adds Graphene crystal grain refined, average grain size drops to 20nm
The composite deposite of the present invention makes coefficient of friction and wear rate reduce simultaneously, has relatively low coefficient of friction, simultaneously
There is the wearability more excellent than cr coating.Under each load, wear rate reduces by more than 50% than matrix.
Specific embodiment
To further illustrate technical scheme below by specific embodiment.
Embodiment 1
A kind of self-lubricating slide rail, this slide rail is formed on the object of drawer incorporating section possessing storage drawer, for from institute
