Abstract

The invention relates to the technical field of post processing of amorphous alloy, in particular to a deburring method of the amorphous alloy. The deburring method includes the following steps: (1) placing the amorphous alloy to be deburred into a closed container with a sparking plug, (2) injecting mixed gas into the closed container, (3) lighting the mixed gas in the step (2) with the sparking plug, enabling the mixed gas to be heated to have a reaction, and controlling the reaction temperature and the reaction time of the mixed gas, and (4) jetting cooling gas to the amorphous alloy after the reaction in the step (3) is finished, and obtaining the amorphous alloy without burrs after cooling is carried out; the heating process and the cooling process are both based on a TTT chart, and the amorphous alloy does not have a crystallization reaction. By means of the deburring method, under the condition that the amorphous alloy does not have the crystallization reaction, the aim of removing the burrs in a quite short time is achieved, the production working hours are greatly reduced, the advantage of being good in deburring effect is achieved, and the quality of an amorphous alloy product is accordingly improved.

Description

technical field [0001] The invention relates to the technical field of post-processing of amorphous alloys, in particular to a method for deburring amorphous alloys. Background technique [0002] Amorphous alloys have been widely used in the fields of electronics, machinery, and chemicals because of their excellent properties in terms of strength, hardness, toughness, wear resistance, corrosion resistance, soft magnetism, and superconductivity. However, amorphous alloys are highly brittle and thus prone to cracking. Due to the characteristics of high hardness and brittleness of amorphous alloys, burrs are prone to occur on the cut surface of amorphous alloys after processing and cutting. In addition, after the amorphous alloy is cast, a small amount of burrs will also appear on the surface of the amorphous alloy. [0003] For the burrs generated during casting or post-processing of amorphous alloys, if not removed, it will seriously affect the quality of amorphous alloy pr...
