Abstract

The invention discloses a method used rod plasma spraying to manufacture iron base amorphous alloy. Ingot iron, industry iron boron and silicon iron are smelted to master alloy in proportion in induction furnace. Then it is formed into crystalline state alloy rod with 2mm-4mm diameter. The crystalline state alloy rod is sprayed to cooled copper stick to form iron base amorphous alloy by aerospace plasma spraying method. The invention overcomes the technique bias that the amorphous alloy powder can only be used in the manufacturing course. The formed amorphous alloy material has high amorphous content, hardness, good wearing qualities, and magnetic property.

Description

technical field

[0001] The invention belongs to the technical field of metal material preparation, and relates to a method for preparing an iron-based amorphous alloy, in particular to a method for preparing an iron-based amorphous alloy by plasma spraying of rods. Background technique

[0002] Amorphous alloys refer to metal alloys with short-range order and long-range disorder in the arrangement of atoms in the solid state, also known as metallic glasses. Due to the excellent properties of amorphous alloys, such as high strength, high toughness, high hardness, extremely high corrosion resistance, soft magnetic properties, low temperature coefficient of resistance and high room temperature resistivity, etc., it is a promising new type of alloy. Material.

[0003] In the preparation of amorphous alloys, due to the conventional cooling rate, metals and their alloys generally exist in a stable crystalline state, amorphous alloys can only be formed under non-equilibrium condit...
