Abstract
The utility model relates to a piston ring with a non-stick coating. The piston ring comprises a first ring. The utility model belongs to the technical field of manufacturing of piston rings. The piston ring is mainly characterized in that the polytetrafluoroethylene non-stick coating is coated on a base layer of the piston ring by using the property of low friction coefficient of the non-stick coating; and the coating is stable in performance and good in using performance, and is favorable for improving the economical efficiency of an engine, improving the initial running-in property and prolonging the service life of the engine. The friction coefficient can be reduced to 0.04-0.09 at most, and the aim of reducing the loss of friction work is fulfilled; and the adhesive wear resistance of the engine is improved by using the polytetrafluoroethylene non-stick coating with low surface tension. A powerful guarantee is provided for normal work of the engine under the conditions of continuously improved explosion pressure and power per liter, emission standard of the engine in national policies and legislations is continuously improved, and the environment is effectively improved.
Description
Technical field
The utility model relates to a kind of piston ring with non-sticking lining, and its application comprises the first road ring.Belong to piston ring manufacturing technology field.
Background technique
Hyundai Motor requires motor to have higher power, lower fuel oil consumes and longer working life, and further reduces the burden of mechanical transport to environment, and petrol engine and diesel engine manufacturers being are all constantly are being researched and developed for pursuing this target for this reason.For adapting to this engine technology development trend, the components supplying merchant is carrying out deep research aspect petrol engine and the piston ring of diesel engine surface treatment.The friction power loss of motor can produce material impact to fuel consume.And because the combustion efficiency of present engine improves constantly, the engine friction power consumption highlights the influence of oil consumption day by day.The main source of modern engine friction power loss is a piston assembly, comprises piston and piston ring, and piston ring principal element especially.Under extreme condition such as high temperature during in igniting of motor initial stage running in stage and motor, highly corrosive, the lubricant film between piston ring and cylinder sleeve friction surface is difficult to effective foundation, along with improving constantly of engine flare pressure; Lubricant film between the piston ring-cylinder liner friction pair is set up the more and more difficulty that becomes; In the moment of engine operation initial stage and igniting, dry friction appears in oil film even can't set up; Cause the piston ring-cylinder liner friction pair to lose efficacy the motor cisco unity malfunction.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned existing technology, and a kind of piston ring with non-sticking lining is provided, and is intended to overcome the above-mentioned defective of existing in prior technology, reaches the antisticking wearing and tearing that reduce the frictional work loss, improve motor.For motor proper functioning under pressure of explosion that improves constantly and power per liter condition provides sound assurance.
The purpose of the utility model realizes like this that through following technological scheme a kind of piston ring with non-sticking lining comprises the stock of piston ring and the base layer on the stock; Said stock is alloy cast iron or spheroidal graphite cast iron or alloy steel or stainless steel, and said base layer is cementation coating or coating; Said cementation coating is a nitriding layer, and coating is chromium coating or chrome-base ceramic composite plating layer or PVD coating, it is characterized in that, on the base layer of piston ring, scribbles Anti-Adherence Coating of Polytetrafluoroethylene.
The thickness of Anti-Adherence Coating of Polytetrafluoroethylene is 6～18 μ m.
The utility model utilizes the little characteristics of Anti-Adherence Coating of Polytetrafluoroethylene friction ractor; It is sprayed on the base layer of piston ring, and the utility model coating performance is stable, usability is good, helps improving the Economy of motor; Improve initial fitting property, prolong motor working life.Can the friction factor maximum be reduced to 0.04～0.09, reach the purpose that reduces the frictional work loss; Utilize the little Anti-Adherence Coating of Polytetrafluoroethylene of surface tension, improve the antisticking wearing and tearing of motor.For motor proper functioning under pressure of explosion that improves constantly and power per liter condition provides sound assurance, satisfied the national policy rules to the improving constantly of engine emission standard, effectively improved environment.
Description of drawings
Fig. 1 is one of the utility model sectional structure schematic representation, and its base layer is a cementation coating.
Fig. 2 is two of the utility model sectional structure schematic representation, and its base layer is a coating.
Among the figure, 1 Anti-Adherence Coating of Polytetrafluoroethylene, 2 cementation coatings or coating, 3 stocks.
Embodiment
Further specify the utility model in conjunction with accompanying drawing and embodiment; Shown in Figure 1 as shining; The utility model is by the base layer on piston ring stock 3 and the stock 3, and this routine base layer is a cementation coating 2, and said stock 3 is a stainless steel; Said cementation coating 2 is a nitriding layer, spraying Anti-Adherence Coating of Polytetrafluoroethylene 1 on the cementation coating 2 of piston ring.
Shown in Figure 2 as shining; The utility model is by the base layer on piston ring stock 3 and the stock 3; This routine base layer is a coating 2; Said stock 3 is alloy cast iron or spheroidal graphite cast iron or alloy steel or stainless steel, and said coating 2 is chromium coating or chrome-base ceramic composite plating layer or PVD coating, spraying Anti-Adherence Coating of Polytetrafluoroethylene 1 on the coating 2 of piston ring.
The thickness of Anti-Adherence Coating of Polytetrafluoroethylene is 6～18 μ m.Piston ring and cylinder sleeve utilization and the Anti-Adherence Coating of Polytetrafluoroethylene that surface tension is little, friction ractor is little, corrosion resistance is good reduce to 0.04～0.09 with the friction factor maximum, reach the purpose that reduces frictional work loss and antisticking wearing and tearing, improve the Economy of motor.
Under extreme condition such as high temperature during in igniting of motor initial stage running in stage and motor, high pressure, highly corrosive, the outermost polytetrafluorethylecoatings coatings in piston ring excircle surface forms lubricating film.After lubricating film between the piston ring-cylinder liner friction pair forms, improved the friction condition of former base layer, made obtain prolonging the working life of polytetrafluorethylecoatings coatings piston ring.
The Anti-Adherence Coating of Polytetrafluoroethylene piston ring is that motor proper functioning under pressure of explosion that improves constantly and power per liter condition provides sound assurance, reaches and satisfies the target that improve constantly, effectively improve environment of national policy rules to the engine emission standard.
