Embodiment 1
[0033] An 8wt% aluminum-magnesium alloy plate with a flow field of 30cm×50cm×10cm is selected, the flow channel is 1cm deep, 1cm wide, and the ridge width is 1cm. After cleaning the aluminum-magnesium alloy plate, ultrasonically oscillate with ethanol and deionized water for 5 minutes in sequence, then configure 0.1mol / L sodium chloride solution as the electrolyte solution, use graphite as the cathode, and the aluminum-magnesium alloy plate as the anode, apply at room temperature Direct current, the current density is 100A / m 2 , The voltage is 200V, and the electrochemical corrosion time is 120mins. The corroded aluminum-magnesium alloy plate was washed with ethanol and deionized water three times in sequence. Put it into an oven for vacuum drying at a temperature of 60° C. for 3 hours.
[0034] Mix copper powder, indium powder, and germanium powder at a mass ratio of 1:1:1 for 2 hours to obtain a mixed powder, and put it into the powder feeder of the plasma spraying equipme...
