Abstract
The utility model discloses a piston ring embedded with pure oxide ceramic, which belongs to the field of piston ring technologies and surface treatment, and is mainly suitable for manufacturing a sealing gas ring for an internal combustion engine piston with a pure oxide ceramic coating. Processes, such as grooving, hot spraying of pure oxide ceramic, grinding and the like are performed on the outer circle surface of the ordinary sealing ring, so that an embedding layer of a pure oxide ceramic coating is formed on the outer surface of a metal piston ring. An oxide material has the properties of high hardness, high wear resistance, low wear, low friction coefficient and the like, so that the service life of the sealing gas ring is prolonged, and the energy consumption of an internal combustion engine is lowered. The piston ring can be widely applied to various internal combustion engines, so that the internal combustion engines have the advantages of low oil consumption, low emission and long service life.
Description
Technical field
The utility model relates to the surface treatment of internal-combustion engine piston ring, belongs to piston ring technology and field of surface treatment.
Background technique
Current ic engine industry field is handled the main modes such as surface spraying Mo and NiCrBSi alloy mixed powder, electroplating Cr onto surface, surface infiltration, embedded with metal-ceramic composite that adopt to internal combustion engine with the seal ring outer round surface.Because Mo is a scarce resource and relatively low through its hardness of surface and the wear resistance of the processing of thermal spraying Mo-NiCrBSi alloyed powder; Though electrochromism hardness and wear resistance are higher, there is serious pollution problem; Surface infiltration layer is thinner, and less stable; Then there is the more weak problem of the combination force between tesserae metal and pottery in embedded with metal-ceramic composite.
Along with the development of heavy industry such as machine-building, automobile, boats and ships, big machinery etc. improve day by day to the requirement of internal-combustion engine.The continuous growth of social demand such as energy problem, environmental issue need further improve existing internal combustion engine system technology for making.
Summary of the invention
In order to reduce the manufacture cost of piston ring, reduce the consumption of scarce resource, improve piston ring usability, increase the service life, reduce pollution, energy efficient, the utility model provides a kind of pure-oxide Ceramic piston ring of inlaying.
Implementation of the present utility model is at first to adopt the machining mode to offer embedding groove on the piston ring ring body; Adopt the thermal spraying mode to spray the pure-oxide pottery then in the embedding groove of offering in advance, this pure-oxide pottery is the mixing of fusion or the multiple metallic oxide and the fusion thereof of a kind of metallic oxide or multiple metallic oxide; Be ground to the use size at last, and guarantee that the thickness of pure-oxide pottery mosaic coating is 0.05～1mm.
The utility model is simple in structure, and manufacturability is strong, adopts the piston ring of the utility model manufacturing to have wear-resistant, low friction, long characteristics of life-span.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Fig. 1 A-A cross-sectional view;
Among the figure: 1 piston ring ring body; The pure-oxide pottery mosaic coating of 2 sprayings.
Embodiment:
1, at the piston ring ring body 1 outer surface car embedding groove of spheroidal graphite cast iron or alloy cast iron;
2, adopt the mode of thermal spraying to spray at piston ring face and strengthen aluminium oxide titanium pottery;
3, the grinding outer surface is to using size and guaranteeing that the thickness of pure-oxide pottery mosaic coating 2 is 0.05～1mm.
Claims (1)
1. inlay pure-oxide Ceramic piston ring for one kind, comprise ring body, it is characterized in that described ring body cylindrical is provided with embedding groove, be provided with the coating of pure-oxide pottery in the embedding groove, the thickness that the pure-oxide pottery is inlayed coating is 0.05 ~ 1 millimeter.
