Abstract
The utility model relates to a sealing ring of a supercharger. The purpose is to provide a sealing ring with a self-lubricating function, wherein the surface density of the sealing ring is high, the toughness is good, and the sealing ring is wear resistant. According to the utility model, the composite ceramic sealing ring of a supercharger comprises a ring core, the external surface of the ring core is provided with a cermet layer, the cermet layer is formed by penetration on the surface of metal employing an ultramicro low-temperature plasma chemical vapor deposition technique, and thereby the toughness and abrasive resistance of the sealing ring are raised.
Description
Technical field
The utility model relates to a kind of internal-combustion engine booster, particularly a kind of pressurized machine seal ring.
Background technique
Pressurized machine is the core component of motor, it improves engine chamber air density for motor provides pressurized air, enhanced burning chamber oil inflame intensity, its quality is directly connected to the output power height of internal-combustion engine, present various model internal-combustion engine is all pursued high-output power, especially now heavy duty and long-distance transport require to increase the output power of motor, providing the air of high compression by pressurized machine to motor is one of important channel of improving engine output, this is to the toughness as the pressurized machine seal ring of pressurized air critical piece, hardness, wear resistance and anti-attrition are had higher requirement, wearing and tearing in use easily appear in traditional pure metal seal ring, cause large-area leakage of oil, the serious dead and rotor of carbon distribution that causes is swept thorax, becomes the hidden danger of transportation safety.
The model utility content
The utility model provides that a kind of surface density is high, good toughness, wear-resisting and band be from moistening the pressurized machine seal ring of function.
The utility model composite ceramics pressurized machine seal ring comprises ring core, and described ring core outer surface adopts vacuum ultra micro low-temperature plasma chemical meteorology deposition technological penetration to generate cermet coating.
The utility model cermet coating of adopting the micro crystal of a kind of directional diffusion that ultra micro low-temperature plasma chemical meteorology deposition technological penetration generates and network structure on the surface of pressurized machine seal ring and depositing compared with prior art, this layer makes the Surface Microstructure of seal ring finer and close, hardness improves more than 50%, selflubricating, the sealability of sealing ring are significantly improved, elastic force improves greatly, toughness and wear resistance also improve greatly, meet the high-power requirement of motor.
The utility model composite ceramics pressurized machine seal ring, the deposition degree of depth of wherein said cermet coating are 21-29 μ m, and increasing thickness is 2 μ m.Cermet coating adopts this thickness both can reach the requirement that improves wear resistance, toughness, self-enrichment, hardness, can reduce process costs again.
Below in conjunction with accompanying drawing the utility model composite ceramics pressurized machine seal ring is described further.
Description of drawings
Fig. 1 is the utility model composite ceramics pressurized machine seal ring axonometric drawing;
Fig. 2 is the utility model composite ceramics pressurized machine seal ring sectional view.
Embodiment
As shown in Figures 1 and 2, the utility model composite ceramics pressurized machine seal ring comprises ring core 1, ring core 1 outer surface arranges cermet coating 2, cermet coating 2 is the metal ceramics thin films that adopt the micro crystal of a kind of directional diffusion that plasma chemical vapor phase deposition technology under 300 ℃ of conditions of vacuum generates in the metal surface infiltration and network structure and deposit, the generative process of metal ceramics thin film is under the condition of 300 ℃ in vacuum, with nitrogen, silicon, boron gas passes into the working room, under the effect of High Voltage electric field, high temperature, electronics and working gas molecule at a high speed collides, make gaseous nitrogen, silicon, boron becomes high-speed ion, the metal ion on high-speed ion and seal ring surface interacts, generate the network-like ionic structure of BN-SIN, the deposition degree of depth of cermet coating 2 is 25 μ m, increasing thickness is 2 μ m, increasing thickness is the thickness that cermet coating 2 increases the metal surface in the metal surface deposition, deposit thickness refers in cermet coating 2 forming processes because the diffusion stupalith diffuses to form the successive sedimentation layer thickness of being close to cermet coating 2 in metal, the thickness of sedimentary deposit generally is 25 μ m, cermet coating 2 makes the Surface Microstructure of seal ring finer and close, hardness improves more than 50%, degree of finish improves a technology progression, descend more than 10% with the friction factor of annular groove, also with self-lubricating function, anti-attrition of the present utility model, sealing significantly improves, elastic force is strengthened greatly, frangibility not in assembling and transportation process, the rate of fault of pressurized machine is reduced, leakage of oil carbon distribution phenomenon reduces, prolong working life, effectively improved the air compressing efficient of pressurized machine.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
