Embodiment 1
[0064] The manufacturing method of the high-entropy alloy member provided in this embodiment is specifically as follows:
[0065] The first step is to provide LM-X150A equipment from Tianjin Raiming Laser Technology Co., Ltd., vacuumize, fill with argon, and preheat the substrate to 80°C.
[0066] In the second step, the metal powder is mixed with a planetary ball mill and dried in a vacuum drying oven. The metal powder includes Al, Co, Cr, Fe, and Ni in an atomic ratio of 0.3:1:1:1:1. The particle size of the metal powder is 25 μm to 38 μm.
[0067] The rotational speed of the planetary ball mill is 100r / min, and the time for the planetary ball mill to mix metal powder is 1h. The temperature of the drying treatment is 60° C., and the time of the drying treatment is 4 hours.
[0068] In the third step, the metal powder is loaded into the powder bin of the LM-X150A equipment, and the metal powder is laid on the substrate.
[0069] In the fourth step, the laser is used to se...
