Abstract
The utility model relates to a composite material for an oil cylinder body, comprising a metal layer, a ceramic layer and a metal-ceramic blended composite layer between the metal layer and the ceramic layer; and the metal-ceramic blended composite layer accounts for 50 to 60 percents of the total thickness of the composite material. The composite material has the advantages of wear resistance, high temperature resistance, corrosion resistance, a certain toughness and the like, a hydraulic cylinder which is manufactured from the metal/ceramic three-layered composite material can effectively prevent the inner wall of the hydraulic cylinder from being scratched and relieving pressure caused by the long-termed wear of a piston, so that the hydraulic cylinder works more stable and reliably, the service life is longer, the repair cost is lower and the scope of use is wider.
Description
[technical field]
The utility model relates to a kind of composite, is specifically related to a kind of cylinder block composite.
[background technology]
For traditional hydraulic jack, its raw material are mainly steel, processing technology mainly is turning, welding, honed surface again, even its wearability of steel material through quenching and Carburization Treatment is also very low, and the roughness of the inner surface of cylinder block that honing technique is processed is relatively very high, this just causes the conventional hydraulic oil cylinder along with increase service time, and hydraulic cylinder inwall and wearing for piston are serious day by day, causes oil cylinder to produce leakage of oil, pressure release because of scratch.In order to solve the wear-resisting problem of hydraulic cylinder, the method that generally adopts is that the hydraulic cylinder inwall is carried out roll extrusion, high-frequency quenching, chromium plating, laser treatment or the like at present, but these technology costs are higher relatively, and the wearability to hydraulic cylinder promotes also little, use after about 2 years still heavy wear can occur, even scrap.
Therefore, for avoiding the problems referred to above, necessaryly provide a kind of novel oil cylinder cylinder body composite, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of collection high abrasion, high rigidity, anticorrosive by force, and metal high tenacity, high ductibility are in the cylinder block composite of one.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of cylinder block composite, it comprises metal level, ceramic layer and the cermet blend composite bed between metal level and ceramic layer, and cermet blend composite bed accounts for the 50-60% of composite gross thickness.
Cylinder block of the present utility model further is set to composite: described metal level is identical with the thickness of ceramic layer.
Compared with prior art, the utlity model has following beneficial effect: cylinder block of the present utility model has wear-resisting, high temperature resistant, corrosion-resistant with composite and has advantages such as certain toughness, use the hydraulic cylinder of this metal/ceramic 3-layer composite material manufacturing can prevent effectively that the long-term friction of piston from causing the scratch and the pressure release of hydraulic cylinder inwall, make hydraulic cylinder works more reliable and more stable, longer service life, maintenance cost is lower, and range of application is wider.
Simultaneously, cermet blend composite bed is between metal level and ceramic layer, on the one hand relaxed the conflict between two kinds of different materials different performances, mode by physics infiltration and chemical reaction can well combine metal level and ceramic layer on the other hand, promote power and hot transmission between two kinds of different materials, effectively improve the composite performance of material.The modulus of pottery is much larger than metal, the toughness of metal is better than pottery, not only contain metal ingredient but also contain ceramic component in the ceramic/metal transition zone, weakened the sudden change on metal level and the ceramic layer structure, weakened the gap between the overall modulus of ceramic/metal transition zone and metal level, the ceramic layer, reduce the residual stress that metal level, ceramic layer structure produce under external force, improved the anti-vibration performance of material.
[description of drawings]
Fig. 1 is the structural representation of cylinder block of the present utility model with composite.
[specific embodiment]
See also shown in the Figure of description 1, the utility model is a kind of cylinder block composite, and it comprises metal level 1, ceramic layer 2 and the cermet blend composite bed 3 between metal level 1 and ceramic layer 2.Described cermet blend composite bed 3 accounts for the 50-60% of composite gross thickness.Described metal level 1 is identical with the thickness of ceramic layer 2.
Adopting above-mentioned composite to make internal diameter 20mm hydraulic jack obtains with use test after testing: do not have any damage at 900 ℃ of high temperature lower cylinder bodies; Inboard wall of cylinder block did not have any corrosion phenomenon in 72 hours at the concentrated sulfuric acid and concentrated hydrochloric acid effect; With the plunger pole supporting under 300Mpa pressure 500,000 inboard wall of cylinder block of continuous operation do not have any noticeable wear sign.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
