CuAl amorphous alloy and preparation method and application thereof

Abstract

The invention provides a CuAl amorphous alloy and a preparation method and application thereof.The preparation method comprises the steps that (1) a 3D printing model of the CuAl amorphous alloy is designed, then layered slicing is conducted, and a layered slicing result is imported into a 3D printing program; and (2) the CuAl alloy powder is subjected to 3D printing, and the CuAl amorphous alloy is obtained. The laser power of 3D printing ranges from 215 W to 255 W, the scanning speed ranges from 700 mm / s to 1100 mm / s, and the scanning interval ranges from 0.06 mm to 0.08 mm. According to the method, by optimizing technological parameters of 3D printing and combining control over parameters of the lattice structure, direct manufacturing of the CuAl amorphous alloy structural part is achieved, the advantages of being high in density, low in porosity and the like are achieved, meanwhile, the lattice structure of the CuAl amorphous alloy has the characteristics of being variable in porosity, large in specific surface area and the like, and the requirement for efficient industrial catalysis is met.
