Abstract
The utility model discloses a lubricated piston ring, which comprises a piston ring main body, a head and a tail, wherein two ends of the piston ring main body are set as the head and the tail. The lubricated piston ring is characterized in that a surface coating which is made of molybdenum disulfide is arranged outside the piston ring main body; and the thickness of the surface coating is between 0.5 mu m and 0.7 mu m. By arranging the surface coating outside the piston ring main body, the lubricated piston ring is high in abrasion resistance and anti-friction performance, free from harmful ingredients, safe and environment-friendly, the friction performance and abrasion performance of a product are greatly improved, and a good using effect is provided for a customer.
Description
Technical field
The utility model relates to a kind of lubricated piston ring, is specifically related to a kind of piston ring with coating, belongs to the technical field of component of machine.
Background technique
Piston ring is the vital part of motor car engine, and piston ring is a vital part of internal-combustion engine heart, and its surface treatment quality directly has influence on the performance of internal-combustion engine, and is therefore very important to the processing of piston ring.
For adapting to the needs of motor car engine development; Must solve the problem of piston ring friction, wearing and tearing aspect; The main cause that coating piston ring lost efficacy is that fragility is peeled off and fatigue wear; In order to improve the fuel oil consumption of motor, must make fuel oil in cylinder, carry out efficient burning, as much as possible burning energy is nondestructively effectively utilized as driving force.Reduce friction and can directly reduce the loss of this energy, it is directly connected to the improvement of engine fuel consumption, therefore acts on extremely important.
But these sliding positions are in harsh boundary lubrication condition mostly, therefore when requiring low friction, also require to have high wear-resisting property.The friction of piston/piston ring part increases along with the rising of engine speed, accounts for 40-50% in the motor total friction head.
The model utility content
The purpose of the utility model is, a kind of lubricated piston ring is provided, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
The technical problem of the required solution of the utility model, can realize through following technological scheme:
A kind of lubricated piston ring, it comprises: piston ring main body, head, afterbody, the two ends of said piston ring main body are set to head and afterbody, it is characterized in that, and said piston ring main body is provided with the cover coat of molybdenum disulfide outward.
Wherein, the thickness of said cover coat is 0.5～0.7 μ m.
Further, the preferred thickness of said cover coat is 0.5 μ m.
The beneficial effect of the utility model:
The utility model adopts tungsten disulfide WS
2Cover coat reduce friction factor, reduce wear, interlock etc.Overcome or reduce the mechanical lubrication problem, improve the working efficiency and the working life of machinery.Have elimination or reduce many device maintenance, the maintenance issues that causes by friction, abrasion etc.
Normal loading reaches 100,000PSI (or identical with the bearing capacity of base material).
Operating temperature range is wide, from-273 ℃ to 60.50 ℃.
There is not any oxious component, safety and environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the cross section AA of Fig. 1 is to sectional view.
Reference character:
Piston ring main body 100, head 200, afterbody 300 and cover coat 400.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
The experimental technique of unreceipted actual conditions in the following example, usually according to normal condition, or the condition that manufacturer provides is carried out.
Embodiment 1
A kind of lubricated piston ring, as depicted in figs. 1 and 2, comprising: piston ring main body 100, can adopt the casting of iron or stainless steel to form.
The two ends of piston ring main body 100 are set to head 200 and afterbody 300.
The piston ring main body is provided with the cover coat 400 of molybdenum disulfide outward.
The thickness of cover coat 400 is 0.5～0.7 μ m, and cover coat 400 preferred thickness are 0.5 μ m.
This piston ring side perspective effect that shows among Fig. 1.Fig. 2 is the cross-sectional view of Fig. 1, and is to the sectional view enlarged view along AA.
The preparation process and method of the utility model:
The utility model piston ring main body 100 is first-selected base material with die steel, through the ultrasonic cleaning oil removing, subsequently with MEVVA source ion injection technique (metal vapor vacuum arc source technology); TiN is attached to the die steel surface; Form the lubricating film base layer, layer thickness is 0.005 μ m, then on the coating of TiN base; Radio-frequency sputtering mode with in the physical gas phase deposition technology is covered with tungsten disulfide WS
2Coating, layer thickness are 0.5 μ m.The die steel of the lubricated composite bed of the band that obtains has the characteristic of TiN hardness height and favorable anti-corrosion effect; With tungsten disulfide WS
2Low coefficient of friction, greasy property is high, resistant to elevated temperatures comprehensive function.Be applicable to the surface treatment and the processing and fabricating of various moulds, mechanical part, auto parts and components.
Adopt cover coat (tungsten disulfide WS
2) to the surface treatment treatment technology of piston ring main body, prolonged the working life of product.
Tungsten disulfide WS
2Why show good lubricating property and be because: WS
2Crystal has stratiform structure, layer with layer between combination force a little less than, shear easily, slippage, show as low friction coefficient; WS
2Structural stability shows as good resistance high temperature, resistance to extreme pressure ability; Even be higher than under 400 ℃ the temperature environment WS
2Also can form fine and close tungsten oxide (WO through eremacarsis
3) protective layer, suppress WS
2Further oxidation, and tungsten oxide has very low friction factor equally, still can play the effect that the protective money metal surface does not glue together.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
