Embodiment 1
[0021] A method for preparing a foamed aluminum alloy, comprising the steps of:
[0022] 1) Melt the metal aluminum and heat it to 810°C, add a tackifier Ca accounting for 1% of its total mass to the aluminum melt, stir and mix for a reaction time of 15 minutes, so that the melt viscosity is stable;
[0023] 2) Cool the aluminum melt after step 1) to 650°C, add 0.2% of the total mass of the double-coated titanium hydride, and stir at 2000 rpm for 2 minutes. The melt is foamed at a constant temperature, and after the foaming is completed, it can be cooled and solidified by water.
[0024] Among them, the coating method of titanium hydride is to first process titanium hydride through alkaline degreasing, ultrasonic degreasing, sensitization and activation treatment, and then perform electroless iron plating treatment, and then grind and mix titanium hydride coated with iron with alumina made. The mass ratio of iron-coated titanium hydride to alumina is 0.5:0.2.

Embodiment 2
[0027] A method for preparing a foamed aluminum alloy, comprising the steps of:
[0028] 1) Melt the metal aluminum and keep it warm to 830°C, add 1.5% of the viscosity enhancer Ca to the aluminum melt, stir and mix the reaction time for 12 minutes, so that the melt viscosity is stable;
[0029] 2) Cool the aluminum melt after step 1) to 680°C, add 0.6% of the total mass of the double-coated titanium hydride, and stir at 2500 rpm for 4 minutes. The melt is foamed at a constant temperature, and after the foaming is completed, it can be cooled and solidified by water;
[0030] Among them, the coating method of titanium hydride is to first process titanium hydride through alkaline degreasing, ultrasonic degreasing, sensitization and activation treatment, and then perform electroless iron plating treatment, and then grind and mix titanium hydride coated with iron with alumina made. The mass ratio of iron-coated titanium hydride to alumina is 0.8:0.4.

[0033] A method for preparing a foamed aluminum alloy, comprising the steps of:
[0034] 1) Melt the metal aluminum and keep it warm to 840°C, add 2.5% of the viscosity enhancer Ca to the aluminum melt, stir and mix the reaction time for 10 minutes, so that the melt viscosity is stable;
[0035] 2) Cool the aluminum melt after step 1) to 700°C, add 1.8% of the total mass of the double-coated titanium hydride, and stir at 3000 rpm for 8 minutes. The melt is foamed at a constant temperature, and after the foaming is completed, it can be cooled and solidified by water;
[0036] Among them, the coating method of titanium hydride is to first process titanium hydride through alkaline degreasing, ultrasonic degreasing, sensitization and activation treatment, and then perform electroless iron plating treatment, and then grind and mix titanium hydride coated with iron with alumina made. The mass ratio of iron-coated titanium hydride to alumina is 1.5:0.8.
