Embodiment 1
[0054] In the aluminum metal powder, the particle size is 0.1um ~ 100um, add 10% of the total amount of BiCl 3 , carry out ball milling, and the transformation reaction adopted by metal activation modification is as follows:
[0055] Al+BiCl 3 =>AlCl 3 +Bi
[0056] The activated modified metal aluminum alloy fine powder is pressed and sintered at low temperature to prepare the aluminum alloy powder rod.
[0057] Put the above-mentioned aluminum alloy powder rod into a hydrogen reactor filled with seawater, and use such as figure 2 The apparatus shown was used for the reaction. A picosecond laser with a wavelength of 1064nm, a pulse energy of 100 microjoules, and a working frequency of 50Khz is used to pass through the transparent ceramic window of the hydrogen reactor and pass through water. Under the control of a pre-programmed computer program, set the corresponding scanning speed. The layer peels off the alloy powder on the surface of the rotating aluminum alloy powde...
Embodiment 2
[0060] In the aluminum metal powder, the particle size is 0.1um ~ 100um, add 20% of the total amount of SnCl 2 , carry out ball milling, and the transformation reaction adopted by metal activation modification is as follows:
[0061] 2Al+3SnCl 2 =>2AlCl 3 +3Sn
[0062] Aluminum alloy powder rods were prepared by additive manufacturing the activated modified metal aluminum alloy fine powder.
[0063] Put the alloy energy bar obtained above into a hydrogen reactor filled with seawater;
[0064] A picosecond laser with a wavelength of 1064nm, a pulse energy of 100 microjoules, and a working frequency of 50Khz is used to pass through the transparent ceramic window of the hydrogen reactor and penetrate water. Under the control of a pre-programmed computer program, the corresponding scanning is set according to the process conditions. Speed, the alloy powder on the surface of the rotating metal aluminum alloy energy bar is peeled off layer by layer into the water, and the activa...
