Detailed description of the invention
In order to be further appreciated by the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but
Should be appreciated that these describe simply as to further illustrate the features and advantages of the present invention rather than to the claims in the present invention
Limit.
The embodiment of the invention discloses a kind of aluminum alloy anode material, including:
The application, with aluminum as base, with the addition of magnesium, stannum, gallium and rare earth element, and above-mentioned element interacts so that
To aluminum alloy materials as the anode material of air cell, there is preferable chemical property and relatively low corrosion rate.
Magnesium elements has more more negative electrode potential than aluminum, adds alloying element Mg in fine aluminium, makes the negative shifting of current potential and compares
Stable；Add a certain amount of magnesium in alloy system, the decay resistance of aluminium anodes can be improved.But excess Mg Yu Al and alloy unit
The Mg that element reaction generates2Al3For negative electrode phase, when Mg phase compound amounts is more and is enriched with serious at crystal boundary, not only rotten candle electric current
Density increases, and electro-chemical activity reduces.The content of herein described magnesium is 0.1～3wt%, in an embodiment, and described magnesium
Content be preferably 0.5wt%～3wt%, in an embodiment, the content of described magnesium is preferably 1.5wt%～3wt%, more preferably
For 2.5wt%～2.8wt%.
After adding Sn element in aluminium alloy, passivating film surface lower valency A13+By high-valence state Sn4+Replaced, thus produced
One additional hole, destroys the compactness structure of oxide-film, reduces the resistance of oxide-film；Sn can also be with the Mg of excess
Coupling can form Mg2Sn the second phase, these second phases are the sensitive parts of spot corrosion germinating, form more work in discharge process
Property site, thus destroy the seriality of aluminium anodes surface passivated membrane, play activation.But Sn easily forms segregation at crystal boundary
Phase, sn rich phase easily makes crystal boundary preferentially corrode, and increases the corrosion certainly of aluminium anodes, and therefore in aluminium anodes, the addition of Sn element should not surpass
Cross 1.0wt%.The content of stannum described herein is 0.05wt%～1.0wt%, and in an embodiment, the content of described stannum is preferred
For 0.1wt%～1.0wt%, more preferably 0.3wt%～1.0wt%, more preferably 0.5wt%～0.8wt%.
Alloying element Ga can change aluminium grain anisotropy present in the course of dissolution, makes aluminium anodes uniform dissolution；
Simultaneously because Ga fusing point extremely low (29.8 DEG C), it is liquid at alloy surface, there is good fluidity, can monatomic or polyatom
Form enters in alumina diaphragm defect, plays disruptive oxidation film, the effect of stripping oxide-film.Additionally, Ga element can close with other
Gold element such as Sn etc., form eutectic mixture under relatively low operating temperature (60～100 DEG C), destroy aluminum surface nature stable
And the purification membrane of compact structure, but when the content of Ga element is higher than 0.5wt%, certainly corrode aggravation, anode utilization rate reduces.This Shen
In please, the content of gallium be 0.01wt%～0.5wt%, and in an embodiment, the content of described gallium is preferably 0.01～0.2wt%,
In embodiment, the content of described gallium is more preferably 0.02～0.05wt%.
Rare earth has good metamorphism in the alloy, is mainly manifested in crystal grain thinning and dendrite；Rare earth element former
Sub-radius is more than aluminum atomic radius, and Nature comparison is active, is fused to easily fill up in aluminum liquid the surface defect of alloy phase so that new and old
Two-phase interface tension force reduces, and improves the speed of growth of nucleus, the most also forms surface-active film between crystal grain and aluminium alloy,
The crystal grain generated is stoped to be grown up, the homogeneous corrosion of refining alloy tissue, beneficially aluminium anodes；Add rare earth and can improve aluminium alloy
The nodularization of the physicochemical properties, beneficially nonmetal inclusion such as melt and the surface tension of slag, mobility, viscosity, promotes it
Float, such that it is able to effectively remove nonmetal inclusion；Rare earth existence form in aluminium alloy specifically includes that and is solid-solubilized in matrix Al
In, segregation, at phase boundary, crystal boundary and dendrite circle, is solid-solubilized in compound or exists with compound form, its existence form and addition
Amount has the biggest relation；Rare earth element dissolubility in aluminum is the least, and such as La and Ce, in aluminum, dissolubility is less than 0.05%, excessive
It is added with and is likely to result in rare earth element and is enriched with at crystal boundary, stop other alloying element to aluminum lattice diffusion, reduce other alloys unit
The dissolubility in Al solid solution such as element Mg, Sn, Ga.It addition, rare earth element add membership change aluminum surface film oxide structure and
Performance, enters in the space of surface film oxide, have impact on the interaction between atom, make the stability of oxide-film strengthen, and protects
Protect aluminum substrate, improve the decay resistance of aluminium alloy；When adding excess more than 2wt%, the oxide-film that formation is fine and close, thus shadow
Ring the dissolving of aluminium alloy, cause passivation.Described RE is preferably selected from one or more in cerium, lanthanum, neodymium, yttrium, erbium, gadolinium, ytterbium and scandium,
More preferably La and Ce in LREE.The content of herein described RE is 0.02wt%～0.1wt%, in embodiment
In, the content of described RE is more preferably 0.02wt%～0.08wt%, more preferably 0.03wt%～0.05wt%.
Present invention also provides the preparation method of described aluminum alloy anode material, comprise the following steps:
Add Mg, Sn, Ga after being melted by Al ingot and carry out supersonic vibration after Al-RE, then stand, cool down, obtain aluminium alloy
Ingot casting；
Carry out Quenching Treatment after the aluminium alloy cast ingot solution treatment that will obtain, then roll, obtain aluminum alloy anode material
Material.
This application provides the preparation method of a kind of aluminum alloy anode material, comprising: at melting-solution treatment-quenching
Reason-rolling, has finally given aluminum alloy anode material.
According to the present invention, first carry out the process of melting, will to add Mg, Sn, Ga laggard with Al-RE after the fusing of Al ingot
Row supersonic vibration, then stand, cool down, obtain aluminium alloy cast ingot.In above process, during melting, Under Ultrasonic Vibration has been introduced
Dynamic, Mg, Sn, Ga will be added after the fusing of Al ingot and carry out supersonic vibration again after Al-RE；Wherein Al-RE aluminum rare earth intermediate alloy
Can synthesize voluntarily or buying on the market, in Al-RE the mass fraction of RE 0%～50% scope, preferably 10～30%.
Rare earth element and compound thereof diffusion velocity in fusion-casting process is slow so that rare earth addition reach saturated solid solubility it
Before, just there are part thick rare earth granule or intermetallic compound to result from intracrystalline and crystal boundary, though also the fewest by heat treatment
There is solid solution in part, major part still remains in crystal boundary, in needle-like or discontinuously net distribution, makes alloy structure uneven, therefore leads to
Cross supersonic vibration and improve the raising for the decay resistance of alloy of rare earth compound dissolving in aluminium alloy and distribution situation
Most important；Supersonic vibration simultaneously produces a certain degree of impact to metal solidification process, is the alloy preparation side of a kind of environmental protection
Method, carries out supersound process to melt in Solidified Process of Aluminum Alloys, can obtain the most tiny etc. with refining alloy ingot structure
Axialite tissue, the also effect of degasification, be conducive to putting forward heavy alloyed combination property.
