Description
Technical field
It the utility model is related to mini refrigerating machine technical field, and in particular to one kind is used to improve work in mini refrigerating machine
Fill in surface abrasion resistance and the coating structure of mini refrigerating machine reliability.
Background technology
At present, the piston face position of mini refrigerating machine be usually using polymer matrix wear-resistant coating sprayed or
The method of bonding improves piston face wearability, and these methods are all due to that coating hardness is relatively low and cause piston for a long time
Wear more serious after work and fail, reduce the reliability that piston uses, the final reliability for influenceing mini refrigerating machine.
Utility model content
The purpose of this utility model is to provide a kind of coating structure for improving piston face wearability, and the structure can solve
Certainly the deficiencies in the prior art, the wearability of piston face and the reliability of mini refrigerating machine are effectively improved, there is letter
The features such as single, reliable, practical.
To achieve the above object, the utility model employs following technical scheme：
It is a kind of to improve the coating structure of piston face wearability, including piston matrix and it is wrapped in work successively from inside to outside
Fill in the tungsten carbide coating and diamond-film-like on matrix lateral wall；The thickness of the tungsten carbide coating is 10 μm, the diamond-like
The thickness of stone film is 3 μm.
Further, the cylindricity of the tungsten carbide coating is less than or equal to 3 μm.
Further, the piston matrix uses high-speed tool steel.
Further, the tungsten carbide coating uses supersonic spray coating in piston matrix surface.
Further, the diamond-like film uses plasma reinforced chemical vapour deposition on tungsten carbide coating surface.
From above technical scheme, the utility model is applied by setting gradually tungsten carbide on the lateral wall of piston matrix
Layer and diamond-film-like, using the high rigidity of tungsten carbide coating and the wearability of diamond-like carbon film layer, effectively increase piston table
The wearability in face；And the tungsten carbide coating of high rigidity has functioned well as transitional function, piston face abrasion can be effectively reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：
1st, piston matrix, 2, tungsten carbide coating, 3, diamond-film-like.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of coating structure of raising piston face wearability as shown in Figure 1, including piston matrix 1 and from inside to outside
The tungsten carbide coating 2 and diamond-film-like 3 being wrapped in successively on the lateral wall of piston matrix 1.What tungsten carbide coating 2 protruded is high hard
Performance is spent, what diamond-film-like 3 protruded is anti-wear performance, and one layer of tungsten carbide is set between piston matrix 1 and diamond-film-like 3
Coating 2, it is on the one hand to preferably protect piston matrix 1, on the other hand the wearability for diamond-film-like 3, which plays, supported
The effect of crossing, because diamond-like carbon film layer is relatively thin.The thickness of the tungsten carbide coating 2 is 10 μm；Tungsten carbide coating 2 is in preparation process
In if less than 10 μm, then coating is uneven, if greater than 10 μm, is then unfavorable for the attachment of coating and coating, coating and matrix.
The thickness of the diamond-film-like 3 is 3 μm；The sheet that diamond-film-like is prepared by the method for plasma reinforced chemical vapour deposition
Body is than relatively thin, and 3 μm and preferably attachment, too thick then adhesive force weaken, too thin, is worn through quickly.
Further, the cylindricity of the tungsten carbide coating 2 is less than or equal to 3 μm.When the cylindricity of tungsten carbide coating 2 is higher than
At 3 μm, piston can be caused to be increased with the cylinder friction level in refrigeration machine, be unfavorable for the lifting of refrigeration machine Performance And Reliability.
Further, the piston matrix 1 uses high-speed tool steel, and high-speed tool steel material hardness is higher, has certain
Wearability.
Further, the tungsten carbide coating 2 is had using supersonic spray coating in piston matrix surface, supersonic spray coating mode
Beneficial to the attachment of coating and matrix.
Further, the diamond-like film 3 uses plasma reinforced chemical vapour deposition on tungsten carbide coating surface.Deng from
Son enhancing chemical vapor deposition manner, is advantageous to the coating uniform of deposition, and compactness is good.
Manufacturing process of the present utility model is：
First, sandblasting pretreatment is first carried out before being deposited to the outer surface sprayed wc of piston matrix 1 and DLC film, its
The grains of sand of middle sandblasting use the quartz sand of 120 mesh（The purpose of sandblasting is to improve the adhesive force of coating and matrix）, in process
Piston matrix surface after mixed organic solvents cleaning carries out sandblasting, is dried after sandblasting after mixed organic solvents clean（Mixing
Organic solvent cleaning is in order to which sand grains, dirt, grease of piston matrix surface etc. are cleaned up, and ensures clean surface）.So
Afterwards, the mode that supersonic spray coating is carried out on the surface of piston matrix 1 sprays the tungsten carbide coatings 2 of one layer of about 20 μ m-thick, while by carbon
Change the thickness of tungsten coating 2 and be machined to 10 μm, cylindricity ensures within 3 μm；The piston matrix of tungsten carbide coating 2 will be finally coated with
1 by mixed organic solvents cleaning, soap lye cleaning, pure water cleaning, deionized water cleaning（A series of this matting be in order to
Debris by surface etc. cleans up）And the plasma reinforced chemical vapour deposition of DLC film layer 3, wherein DLC film are carried out after drying
Thickness degree is maintained at 3 μm.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
