Sleeve is the hollow cylindrical member in a kind of revolving parts, is a class part common in mechanized equipment, and apply very wide in all kinds of machine, main rising is supported or leading role.Common sleeve part have the various forms of race ring of supporting rotating shaft or axle sleeve, drill jig guide the drill bushing of drill bit, mould die holder coordinate with guide pillar together with in order to the valve pocket etc. of the cylinder liner on the guide pin bushing of locating and lead, internal-combustion engine, oil hydraulic cylinder in hydraulic system, electrohydraulic control.The outer round surface of sleeve matches with the mounting hole of frame, die holder or casing mainly with interference or transition fit, plays fixation; Refer to Fig. 1, the inside of sleeve 01 is the endoporus that accommodation plug-in part 02 passes, and plug-in part 02 is generally travel axis, guide pillar, main shaft, piston, guiding valve etc., and matching with plug-in part in shape and the surface of endoporus, mainly play the guiding role or supporting role.
Owing to usually there is relative movement between plug-in part and hub internal bore, therefore their surface can produce and rubs and cause wearing and tearing, thus greatly shortens the working life of sleeve.In order to improve the wear resistance that will improve hub internal bore surface working life of sleeve, the method improving now part surface wear resistance has a lot: the heat treatment of such as quenching, the machine treatment of such as sandblasting, chemical treatment of such as nitriding etc.But these processing methods all also exist their defect separately, such as quench and be not too suitable for non-ferrous metal matrix, sandblasting can reduce the degree of finish of matrix surface, and chemical treatment is difficult to obtain having high hardness, high elastic modulus, excellent resistance to high temperature oxidation and corrosion resistant high abrasion surface concurrently.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of high abrasion sleeve is provided, it obtains the bore area of high hardness, high elastic modulus and excellent high temperature oxidation resistance by Technology of Chemical Composite Plating, thus improves wear resistance and the antifriction quality of sleeve, increases the service life.
The utility model realizes above-mentioned purpose by following technical solution:
A kind of high abrasion sleeve, has the endoporus holding plug-in part and pass, it is characterized in that: the surface of described endoporus is provided with CrAlN/SiO

2nano laminated coating is by multiple CrAlN layer and SiO
2layer is alternately formed by stacking one by one.
Further, described CrAlN/SiO
2the total thickness of nano laminated coating is 2.2-3.5 μm, and each CrAlN layer thickness is 5nm, each SiO
2layer thickness is 0.5-1.5nm.
Further, described CrAlN/SiO
2nano laminated coating adopts reactive sputtering on the matrix of described high abrasion sleeve, replace sputter and is formed.
Further, the end of the endoporus of described high abrasion sleeve is provided with chamfered section.
Further, all surfaces of described high abrasion sleeve is equipped with CrAlN/SiO
2nano laminated coating.
Further, the shape of described high abrasion sleeve is cylinder.
The utility model adopts reactive sputtering to replace the multiple CrAlN layer of sputter and SiO on matrix
2layer, forms nanometer scale CrAlN/SiO on the surface of sleeve
2laminated coating, after testing, the smooth densification of this cover coat, not only there is the hardness higher than 30GPa and the Young's modulus higher than 350GPa, but also there is excellent oxidation-resistance property and corrosion resistance, substantially improve the wear resistance of sleeve body, corrosion resistance and antifriction quality, thus extend the working life of 2 ~ 3 times.
