[0029] The invention also discloses a preparation process of an aluminum bronze material, comprising the following steps:
[0030] Step 1: preparing an aluminum bronze matrix with pores, which can also be an existing aluminum bronze matrix material;
[0031] Step 2: mixing the oil and nanoparticles to prepare the oil mixture;
[0032] Step 3: ultrasonically mixing the oil mixture and the porous carbon material to obtain a mixture;
[0033] Step 4: Dip the aluminum bronze matrix into the mixture, and infiltrate it under pressure to obtain an aluminum bronze material.
[0034] Preferably, in the third step, the porous carbon material needs to be impregnated in the acid solution for 10-20 minutes in advance.
[0035] Preferably, in step 4, the mixture needs to be pretreated before percolation, specifically adding an anionic surfactant to the mixture and treating it for 10-30 minutes.
[0036] Preferably, the anionic surfactant is a carboxylate type, which is beneficial to nega...
