Description
Technical field
The present invention relates to a kind of novel seawater cell magnesium cathode alloy material.
Background technology
China's magnesium resource is abundant, utilizes magnesium resource to have very important significance.Magnesium alloy quality is light, is widely used in automotive industry, electronics aspect and aerospace.Magnesium alloy electronegativity is good, as sacrificial anode material and once, the negative material of secondary cell is also widely used.There is every year the market demand of 30～40Kt, and with annual 20% speed increment.Magnesium cell is also applied to aerospace, military affairs and the aspect such as biomedical.
The total feature of current negative material used for magnesium alloy is that current potential is negative, hydrogen-separating quantity is low, become mud few, anodic polarization is low, but due to magnesium alloy processing difficulties, uses the general commercial magnesium alloy negative material of main employing of the magnesium alloy negative material in sea-water activated battery in prior art about underwater propeller, shortcoming is that corrosion speed is fast, anode utilization ratio is low, and especially anodizing is serious, makes operating potential be difficult to reach requirement.
Summary of the invention
The present invention is directed to the problem that prior art exists, by adding alloying element design, a kind of novel magnesium alloy is provided, with activated magnesium alloy anode, reduce from corrosion speed and anodic polarization, improve the over-all properties of magnesium alloy negative material, thereby obtain from corrosion speed low, operating potential is born and is stablized the magnesium alloy materials of the flaky excellent property of corrosion product.
The object of the present invention is achieved like this, and a kind of novel seawater cell magnesium cathode alloy material, comprises following mass percent composition: Pb: be 4～6%, Sn is that 2～4%, Ga is 1.5～3.5%, and rare earth 0.1～1.0%, all the other are Mg.
For further optimizing the performance of magnesium alloy materials of the present invention, Pb is that 6%, Sn is that 3%, Ga is 2.5%, rare earth 0.5%, and all the other are Mg.
For further realizing the present invention, magnesium alloy material preparation method for material of the present invention is to adopt resistance smelting furnace that Pb, Sn, Ga are added with pure metal, rare earth adds with master alloy, and adds the moulding of flux casting of metals, then ingot casting is warming up to 250 ± 1 DEG C in box resistance smelting furnace, be incubated 1 hour, continue to be warming up to 280 ± 1 DEG C, be incubated 1 hour, be warming up to subsequently 310 ± 1 DEG C, be incubated 1 hour, continue to heat up 350 ± 1 DEG C, be incubated 1 hour, be finally cooled to room temperature.
In the present invention, add Sn and Ga in magnesium alloy name, after reaction is dissolved, return and be deposited on anode surface, form activation point, make anode be difficult to form continuous, fine and close oxide film, this interaction promotes magnesium alloy negative material still can normally dissolve under the current potential compared with negative and serious anodic polarization does not occur, and interpolation Pb can reduce the operating potential from corrosion speed and stable magnesium alloy negative pole of magnesium alloy significantly; And adding of rare earth can make the crystal grain of alloy careful, composition evenly, further reduces corrosion speed.It is little that the magnesium alloy materials that goes out mentioned component by orthogonal has anodic polarization, and operating potential is negative and stable, low from corrosion speed, corrosion product easily peels off, and the inner uniform crystal particles of alloy is tiny.
