Description
Technical field:
The utility model belongs to technical field of engines, relates to the piston ring structure design.
Background technique:
Piston ring is the motor strength member, and important economic implications is arranged the working life of raising piston ring.
Publication number be CN 1320767A patent disclosure a kind of " nm-class Ti-base ceramic covered piston ring and method thereof ", adopt the metal base surface deposition one deck nm-class Ti-base ceramic coating of PVD technology at piston ring.This technology has improved the wear resistance and the working life of piston ring.But owing to be simple layer film, so thickness can not be too thick, its coating is thinner, within 3 μ m～5 mu m ranges.
Publication number be CN 1470671A patent disclosure a kind of " SiC/TiN super hard nano multilayer film and preparation process thereof ".This invention can obtain SiC/TiN super hard nano film, is applicable to instrument, mould etc.But this multilayer film total thickness only is 2 μ m～4 μ m.
The patent of above-mentioned binomial application, coating are all thinner, and the surface do not have the antifriction layer, use the part that still has some deficits on piston ring.
Summary of the invention
The purpose of this utility model is for overcoming the deficiency of prior art, design a kind of multi-component multi-layer nanometer film piston ring, the one, increase the thickness of piston ring wearing layer, and improve its life time; The 2nd, the antifriction layer of increase piston ring prevents to scratch cylinder sleeve.
A kind of multi-component multi-layer nanometer film piston ring of the utility model design, comprise the piston ring metallic matrix, form pretreatment layer at this metal base surface, it is characterized in that having by the alternate film formed wearing layer of multi-component multi-layer nanometer that is laminated of chromium nitride film with titanium nitride film in this pretreatment layer surface-coated.
The utility model also can be coated with Cuprum alloy or tin alloy again on the wearing layer surface of this piston ring, or teflon, or the friction coat of nylon membrane formation.This antifriction layer thickness can be 3 μ m～10 μ m.
Above-mentioned multi-component multi-layer nanometer film wearing layer can be formed by chromium nitride film alternate with titanium nitride film stacked (CrN/TiN/CrN), and the thickness of every tunic can be 50nm～800nm, and the number of plies of film can be 5 layers～50 layers, and this wearing layer total thickness can be 3 μ m～25 μ m.
Implementation method of the present utility model is: piston ring metallic matrix of the present utility model can adopt materials such as spheroidal graphite cast iron, gray cast iron, stainless steel, spring steel to make.Obtain nitriding layer or carbonitrided case by chemical heat treatment method at the piston ring metal base surface earlier, perhaps obtain the coat of metal or composite deposite by electro-plating method.Above-mentioned infiltration layer or coating are called pretreatment layer.Then in ion surface is handled stove, the target that excites crome metal and metal titanium to make successively with electric arc.Feed N
2, H
2Or NH
3Deng reaction gas, outside the piston ring pretreatment layer, be coated with successively and be covered with CrN/TiN/CrN/ ... the multi-component multi-layer nanometer film constitutes wearing layer.
Because CrN can prepare thicker coating, therefore can obtain the multi-component multi-layer nano-film coating that thickness is 3 μ m～25 μ m, this coating hardness is 1500HV
