Abstract

The present invention discloses a laser 3D printing method of an amorphous alloy composite material. Amorphous alloy composite material alloy powder whose grain size is 20-150 [mu]m is formed into amorphous alloy composite material components through a coaxial powder feeding 3D printing method under the conditions that the laser power is 100-600 W, the scanning speed is 500-1200 mm/min, the laser spot diameter is 0.5-4 mm, the overlap rate is 15-50%, the printing layer thickness is 0.5-2 mm, the printing environment oxygen concentration is lower than 50 ppm, and the substrate preheating temperature is 0-300 DEG C. The amorphous alloy composite material components are annealed for 2-12 hours under the protection of an inert gas and at a temperature of 300-600 DEG C. With adoption of the laser 3D printing method, defects of the amorphous alloy composite material formed through a water quenching method and a copper mold casting method are overcome, the problem that the amorphous alloy composite material is hard to mechanically process is solved, and the method has the advantages of being economical in raw material and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of forming amorphous alloy composite materials, in particular to a method for preparing amorphous alloy composite material components using laser 3D printing technology. Background technique [0002] Amorphous metals combine many excellent properties, such as high strength, high hardness, wear resistance and corrosion resistance. These excellent properties make it have broad application prospects in aerospace, automobile and ship, armor protection, precision instruments, electric power, energy, electronics, biomedicine and other fields. However, the size of the amorphous metal produced by the copper mold casting method commonly used at present is only centimeter-level, which seriously restricts its engineering application. In addition, due to the serious room temperature brittleness of amorphous metals, it is difficult to machine at room temperature, so it is difficult to obtain sophisticated and complex am...
