Description
Technical field
The present invention relates to a kind of aluminum alloy materials that power can be provided to automobile, be specifically related to a kind of Al-Ga-In-Sn-Zn Alloy And Preparation Method and application.
Background technology
Energy-conservation and new-energy automobile is the focus of automobile industry development planning; In the face of increasingly serious energy situation and the environmental protection pressure of global range, the main automobile production in world state is all the vital measure of development new-energy automobile as raising inter-industry competition ability, the Sustainable development of maintenance social economy.In recent years; The utilization of new forms of energy such as sun power, Hydrogen Energy, wind energy, Geothermal energy has obtained developing rapidly; Wherein Hydrogen Energy has wide material sources, clean environment firendly, can store and advantage such as renewable; Be regarded as the most potential clean energy of 21 century, countries in the world are all studied Hydrogen Energy as the strategic energy.
The Hydrogen Energy industrialized utilization is difficult to implement owing to three aspects restrictions such as receiving hydrogen producing technology, storing technology and transportation technology.Aspect hydrogen manufacturing, existing industrial hydrogen mainly adopts fossil oil hydrogen manufacturing, water electrolysis hydrogen production and biological hydrogen production.Be main with fossil oil hydrogen manufacturing wherein, but the raw material of this method 95% comes from fossil oil, fundamentally do not solve the sustainable problem of the energy, and hydrogen production process still produces carbonic acid gas, the improvement of environmental pollution has no help; Aspect storage hydrogen, still lack effectively storage hydrogen mode.As adopt gaseous state storage hydrogen, bulky and energy density is low; As adopt liquid storage hydrogen, then require very low temperature or ultra-high voltage.In addition, the storage tank manufacturing cost is high, and storage tank itself is overweight, and hydrogen-storage amount only accounts for 5%～7% of storage tank quality.Aspect the hydrogen transportation, though hydrogen has potential preferably transportability, it very easily leaks, even vacuum-packed fuel tank, every day, leakage rate still reached 2%.Therefore, effective utilization of Hydrogen Energy receives the technical limitation of above-mentioned three aspects and can't realize.At present, hydrogen mainly contains two kinds of transform modes as the automobile-used energy: with the vehicle fuel battery engine of proton exchange mode and the hydrogen explosive motor that is the basis with existing Vehicular internal combustion engine.Before the vehicle-mounted hydrogen production technology does not break through as yet, have to adopt storing hydrogen as energy source of car, and adopt storing hydrogen to increase vehicle weight greatly as energy source of car, run counter to automobile lightweight developing direction, and security owes poor.
Therefore, dissolve the problems referred to above, realize one of approach that moves the utilization of Hydrogen Energy effective and safe, realize instant hydrogen manufacturing exactly.Promptly adopt cheap controlled hydrogen manufacturing mode, hydrogen manufacturing is at any time used at any time.Existing hydrogen producing technology is difficult to meet vehicle-mounted requirement; So; Seeking new hydrogen producing technology becomes the automobile-used hydrogen source key of problem of solution, and it not only meets the growth requirement of current and following automobile market, and can effectively improve the relevant enterprise competition capability.
Adopt more vehicle-mounted hydrogen production method to be to use borohydride hydrolytic hydrogen production at present, when solution contacts with hydroborate, produce hydrogen immediately, cut off solution and promptly stop hydrogen supply, can conveniently regulate hydrogen output and hydrogen yield, realized vehicle-mounted hydrogen production and instant hydrogen supply.But this method needs expensive catalysts, and the hydrogen manufacturing cost is high, and high cost causes it to be difficult to mass-producing.The U.S. and Muscovite scientist are carrying out many research aspect the duraluminum hydrolytic hydrogen production in recent years.Can improve its reactive behavior as adding some metallic element in the fine aluminium, improve the output and the speed of hydrogen when strengthening aluminium, water reaction, guarantee instant and sufficient supply of hydrogen.So it is the preferred approach that realizes vehicle-mounted hydrogen production that aluminium and water direct reaction prepare hydrogen, mainly shows: carbon-free hydrocarbon compound in (1) preparation process; (2) duraluminum and water are swift in response, and it is hydrogen supply that duraluminum is met water, and anhydrous i.e. termination is not only easy to control but also realized instant hydrogen manufacturing, hydrogen manufacturing as required, does not need or less storage hydrogen, reaches vehicle-mounted requirement; (3) only consume water and aluminium of hydrogen manufacturing, aluminium is converted into white lake or aluminum oxide, converts aluminium again to through electrolysis, constitutes the system that recycles; (4) the hydrogen calorific value is high, about 28700kcal/kg (gasoline is 10630kcal/kg); (5) hydrogen is used for the motor car engine burning, and product is a water, and the water of generation generates hydrogen with reactive aluminum again, constitutes the closed cycle work system, and system compares with open-circuit working, has reduced energy consumption, and has made full use of water, is great progress.Therefore, utilize the duraluminum hydrolytic hydrogen production both can realize instant hydrogen manufacturing, hydrogen manufacturing as required, satisfy vehicle-mounted requirement, can overcome the defective that present main flow process for making hydrogen uses hydrocarbon thing again, realize zero pollutant discharge.
Chinese patent CN101235451A discloses a kind of by 10～90% metallic aluminium and 10～90% GALLIUM metal pure, is equipped with gallium-aluminum alloy through fusion chill casting legal system; CN101497954A discloses two kinds of raw materials of employing gallium aluminium and has prepared gallium-aluminum alloy through vacuum melting method.CN 101613082A discloses two kinds of raw material powders of employing gallium aluminium through the foam metallurgy method, is aided with technology preparation gallium-aluminum alloys such as high pressure, sintering, moulding.
