Description
Technical Field
The invention relates to a drainage chamber, and belongs to the field of metal materials.
Background
The automobile water chamber is an important component of an automobile radiator, is generally arranged at the upper part and the lower part of the radiator and is used for buffering cooling water flowing into a radiator core and conveying the cooling water cooled by the radiator to an engine again to ensure the heat dissipation effect of the engine.
The automobile water chamber can be simply divided into an upper water chamber and a lower water chamber, has single function, is mainly used for storing cooling water and assisting in heat dissipation, and is indispensable.
It follows that the transition assistance function of the lower water chamber in the radiator is also of great importance. The shape of the lower water chamber is determined during preparation, and the shape cannot be optimized, so that the service life of the lower water chamber is prolonged, and the optimization of the material of the lower water chamber is focused on, and the effective service life of the lower water chamber is fundamentally prolonged. The aluminum alloy has better performance.
The aluminum alloy is an alloy system which is formed by adding a certain amount of additive elements such as metal/nonmetal and the like on the basis of aluminum and controlling the content of impurity elements. The aluminum alloy has the advantages of high strength, high hardness, corrosion resistance and light weight, and is suitable for being used as a structural material. But the material composition and smelting process of the traditional aluminum alloy cannot better improve the alloy performance.
In order to overcome the defects of low hardness, poor wear resistance and the like of the traditional alloy, the publication No. CN102121414A discloses an all-aluminum alloy heavy truck water tank, which utilizes aluminum alloy to replace plastic and is made into a water tank through structural change, so that the service life of the water tank is prolonged, the pollution of plastic manufacture to the environment is reduced, and the maintenance and use cost of a user is reduced. However, such a simple material replacement is prone to defects in the manufacturing process, and cannot fundamentally change the performance of the water chamber, and even cannot cope with a complicated use environment.
Disclosure of Invention
In view of the problems, the invention provides a sewage chamber which has higher strength, high hardness and corrosion resistance and can adapt to complex environment.
In order to achieve the purpose, the invention adopts the following technical scheme:
the lower water chamber is made of aluminum alloy, and the aluminum alloy comprises the following raw materials in percentage by mass: cage polysilsesquioxane: 0.5-2.5%, Sr: 0.02 to 0.1%, Zr: 0.15-0.25%, Mn: 0.04-0.1%, Zn: 0.07-0.14%, and the balance of Al and impurities.
Preferably, the cage-type polysilsesquioxane is in the form of particles, and the particle size of the cage-type polysilsesquioxane is 0.5-1.5 mm.
Further preferably, each particle of the cage-type polysilsesquioxane is coated with a copper foil, and the coating form is half-coating or full-coating.
More preferably, the thickness of the copper foil is 6-10 μm, and the volume ratio of the cage-type polysilsesquioxane to the copper foil is 20-30: 1.
According to the invention, cage type polysilsesquioxane is specially added into an aluminum alloy material, the basic attribute of the cage type polysilsesquioxane belongs to inorganic particles, but the silicon element has extensibility and metallicity, and the cage type polysilsesquioxane can be well blended into the aluminum alloy as a reinforcing component in the test process. In the process of developing the aluminum alloy, the whisker growth phenomenon of different degrees can exist when different elements in the aluminum alloy are mixed to form components, the performance of the alloy can be affected to different degrees by excessive growth, microcracks are easily generated after the alloy is formed, the service life of products produced by the alloy is shortened, and meanwhile, the grain refinement is not facilitated, so that the reduction of synthetic metal (such as strength, hardness, resistance and the like) is caused. The power of whisker growth is from oxidation of trace oxygen in the alloy to part of the added elements to generate oxides to further cause volume expansion and generate compressive stress to other surrounding phases, and the cage-type polysilsesquioxane can greatly relieve the oxidation process of the added elements and inhibit the generation of the oxides of the added elements, thereby slowing the whisker growth. The particle size of the cage-type polysilsesquioxane is limited so as to be better blended into the alloy components and avoid layering (insufficient blending) due to too large particle size.
Meanwhile, the cage-type polysilsesquioxane can promote the modification effect of Sr and Zr elements on the alloy, the tensile strength of the alloy at room temperature is improved by more than 25% compared with that before modification, and the Sr element is more easily enriched on the surface layer of the alloy, so that the corrosion resistance of the alloy is further enhanced, and the lower water chamber can deal with the corrosion force generated by cooling water at different temperature differences.
Considering that the inorganic particle property of the cage type polysilsesquioxane is slightly higher than the metal property of the cage type polysilsesquioxane, the copper foil coating treatment is carried out on the outer layer of the cage type polysilsesquioxane, the thickness and the using amount of the copper foil are limited, and the combination degree of the cage type polysilsesquioxane and the alloy can be fully ensured by the copper foil with smaller thickness and lower content. Meanwhile, trace copper element can also enhance the comprehensive performance of the alloy.
The invention also provides another technical scheme while reasonably selecting the material proportion:
a preparation method of a lower water chamber comprises the following steps:
(1) smelting: weighing the raw materials, and mixing and melting all the raw materials except the cage-type polysilsesquioxane to form alloy liquid;
(2) airflow stirring: introducing inert gas into the alloy liquid from the side surface of the alloy liquid, and circulating and repeatedly sieving the alloy liquid from the side surface of the alloy liquid by using a graphite net;
(3) curing and forming: slowly reducing the temperature, adding cage-type polysilsesquioxane particles when the alloy liquid is semisolid slurry, continuously sieving by using a graphite net, and naturally cooling until an alloy block is formed;
(4) and (3) finished product: and machining the alloy block to form the water outlet chamber.
In the preparation process of the lower water chamber, the invention particularly adopts an alloy processing technology of airflow stirring. The air flow stirring is a mode of combining air flow and stirring, strong convection is generated on the alloy liquid by utilizing the air flow, and alloy crystal grains are refined by utilizing a stirring mode of sieving a graphite net, so that a semi-solid structure with good performance is formed, and the elongation of the alloy is greatly enhanced.
Preferably, the temperature during the gas flow stirring is controlled at 600-650 ℃, and the cooling is carried out by using soft metal (such as gallium-indium alloy, tin alloy and the like) during the solidification. The slower cooling rate is kept, so that the cage-type polysilsesquioxane particles can be protected from partial denaturation and partial solidification due to larger temperature difference to form an alloy with non-uniform components.
Preferably, the inert gas in step (2) comprises one or more of argon, helium and neon.
Preferably, in the step (2), bubbles are formed on the upper surface of the alloy liquid without breaking when the gas is introduced from the side.
When gas is introduced, the alloy liquid is in a strong convection and strong stirring state due to the action of bubbles. At this time, the bubbles generate turbulence and apply shear stress to the alloy liquid. In turbulent flow, fluid particles make brownian motion, which causes momentum exchange between different metallic fluid phase particles, thereby creating greater shear stress and losing more efficiency. I.e. to optimize the morphology of the alloy structure.
Preferably, the grid height of the graphite net in the step (2) is not more than the upper surface of the alloy liquid.
Preferably, the inert gas rate in the step (2) is consistent with the sieving rate of the graphite net, and both the inert gas rate and the sieving rate are 0.5-1.5 cm/s.
No matter the bubbling is controlled not to be broken, or the height of the graphite net is not more than the upper surface of the alloy liquid, the purpose is to control the inert gas not to be dissipated from the upper surface of the alloy liquid, so that the structure phase of the alloy is layered, and the outermost alloy phase has higher corrosion resistance.
Compared with the prior art, the invention has the following advantages:
(1) the invention specially adds the cage type polysilsesquioxane as a reinforcing component and inhibits the growth of whiskers.
(2) According to the invention, the copper foil coating treatment is carried out on the outer layer of the cage-type polysilsesquioxane, the thickness and the using amount of the copper foil are limited, and the combination degree of the cage-type polysilsesquioxane and the alloy can be fully ensured by the copper foil with smaller thickness and lower content.
(3) The invention particularly adopts an alloy processing technology of airflow stirring, namely, a mode of combining airflow and stirring is adopted, the airflow is utilized to generate strong convection to alloy liquid, and a stirring mode of sieving a graphite mesh is utilized to refine alloy grains, so that a semi-solid structure with good performance is formed, and the elongation of the alloy is greatly enhanced.
