[0032] This application also provides a method for preparing the aluminum alloy electrode material, including the following steps:
[0033] After the Al ingot is melted, Mg, Sn, Ga and Al-RE are added, then ultrasonically vibrated, and then allowed to stand and cool to obtain an aluminum alloy ingot;
[0034] The obtained aluminum alloy ingot is solid solution treated, quenched, and then rolled to obtain an aluminum alloy electrode material.
[0035] This application provides a method for preparing an aluminum alloy electrode material, which includes: smelting-solution treatment-quenching treatment-rolling, and finally an aluminum alloy electrode material is obtained.
[0036] According to the present invention, the smelting process is first performed, that is, after the Al ingot is melted, Mg, Sn, Ga and Al-RE are added, then ultrasonically vibrated, and then allowed to stand and cool to obtain an aluminum alloy ingot. In the above process, ultrasonic vibration is introduced during t...
Example Embodiment
[0044] Example 1
[0045] Based on an aluminum ingot with a purity of 99.9%, the composition ratios of the aluminum alloy anode are selected as follows: magnesium: 2.6wt%, tin: 0.7wt%, gallium: 0.03wt%, RE (specifically Al-20%Ce): 0.04 wt%, aluminum: balance.
[0046] Place the measured aluminum ingot in a graphite crucible, under the protection of inert gas, wait for the furnace temperature to rise to 735°C to melt the aluminum completely, stir and discharge the slag, and then add other alloy elements wrapped in aluminum foil; introduce 800W power Ultrasonic vibration, the introduction time is 90s, then let it stand for 10 minutes, pour it into a graphite ark and cool it naturally; place the cast aluminum ingot in a resistance furnace at 490℃ for 4 hours and quickly place it in cold water for quenching treatment; The ingot is rolled into a 2mm thick aluminum alloy sheet at 190°C and cut into a working area of 1cm 2 The electrodes are polished smoothly with 400#, 600#, 800#, 100...
