Embodiment 1
[0022] Embodiment 1: the preparation method of the present embodiment porous alloy electrode is as follows:
[0023] (1) Add the above-mentioned powders into the vacuum ball milling tank with a mass percentage of 75% Al powder, 12.5% Ni powder, 10% Cu powder, 2% P powder, and 0.5% La powder, and feed N 2 , put the ball mill jar into the ball mill, the mass ratio of balls to materials is 5:1, the number of revolutions is 100r / min, every 30 minutes of operation, the gap is 10 minutes, and the total time is 120 minutes;
[0024] (2) Use an isostatic press to press, put the mixed material into a mold with a diameter of 15mm, and press it at 20MPa for 20 minutes to form a rough embryo with a diameter of 15mm. Place the rough embryo in a corundum crucible, and then place it in a vacuum high-frequency induction Melt in a melting furnace, keep warm at 900°C for 3 hours in an Ar atmosphere, take out the smelted alloy and cool it, then wire cut it into 1cm 3 Small cube blocks, polish...

[0030] Embodiment 2: the preparation method of the present embodiment porous alloy electrode is as follows:
[0031] (1) Add the above powders into the vacuum ball milling tank with a mass percentage of 55% Al powder, 25% Ni powder, 15% Cu powder, 4% P powder, and 1% La powder, and feed N 2 , put the ball mill jar into the ball mill, the mass ratio of balls to materials is 4:1, the number of revolutions is 150r / min, every 20 minutes of operation, the gap is 15 minutes, and the total time is 110 minutes;
[0032] (2) Use an isostatic press to press, put the mixed material into a mold with a diameter of 15mm, and press it at 15MPa for 30 minutes to form a rough embryo with a diameter of 15mm. Place the rough embryo in a corundum crucible, and then place it in a vacuum high-frequency induction Melted in a melting furnace, kept in an Ar atmosphere at 900°C for 4 hours, took out the smelted alloy and cooled it, and wire-cut it into 1cm 3 Small cube blocks, polished surface oxide l...
Embodiment 3
[0038] Embodiment 3: the preparation method of the present embodiment porous alloy electrode is as follows:
[0039] (1) Add the above-mentioned powders into the vacuum ball milling tank with the mass percentage of 75% Al powder, 7.5% Ni powder, 13.7% Cu powder, 3% P powder, and 0.8% La powder, and feed N 2 , put the ball mill jar into the ball mill, the mass ratio of balls to materials is 6:1, the number of revolutions is 100r / min, every 30 minutes of operation, the gap is 12 minutes, and the total time is 100 minutes;
[0040] (2) Use an isostatic press to press, put the mixed material into a mold with a diameter of 15mm, and press it at 18MPa for 25 minutes to form a rough embryo with a diameter of 15mm. Place the rough embryo in a corundum crucible, and then place it in a vacuum high-frequency induction Melted in a melting furnace, kept in an Ar atmosphere at 900°C for 4 hours, took out the smelted alloy and cooled it, and wire-cut it into 1cm 3 Small cube blocks, polishe...
