Abstract

The invention discloses a method for manufacturing preparing a multilayer amorphous alloy micro part by vacuum diffusion welding. The method comprises the following steps of: carrying out hot press forming on an amorphous alloy material to obtain an amorphous alloy micro part; grinding the formed amorphous alloy micro part to remove flashes; cleaning the amorphous alloy micro part and a silicon die; assembling and fixing the amorphous alloy micro part and the silicon die; placing a fixed workpiece in a vacuum diffusion oven for welding; integrally placing the welded workpiece and silicon die into a container for holding KOH solution; placing the container in hot water and carrying out water bath heating; and enabling the part to fall from the silicon die to obtain the multilayer amorphous alloy micro part. According to the method disclosed by the invention, the problem that the multilayer amorphous alloy micro part is difficult to form by the traditional method can be solved.

Description

technical field [0001] The invention belongs to the field of diffusion welding, and more specifically relates to a method for preparing multilayer amorphous alloy tiny parts by vacuum diffusion welding. Background technique [0002] Amorphous alloys are a major discovery in the field of materials in the 20th century. The atomic arrangement inside the material is a long-range disordered short-range order structure, without defects such as dislocations and grain boundaries. This unique structure makes amorphous alloy materials have many excellent properties, such as high strength, hardness, wear resistance, corrosion resistance, excellent soft magnetic properties, etc., in military, micro / nano manufacturing, sports equipment, optical communications, Optical integration, lasers, new solar cells, high-efficiency magnetic and power transmission materials have broad application prospects. In particular, the amorphous alloy has superplastic properties in the supercooled liquid pha...
