Embodiment 1

[0038] See figure 1 and Figure 4 . A method for deburring amorphous alloys in this embodiment uses the electrode 1 to release the 100J electric energy stored in the capacitor 2, and uses the electric energy released by the electrode 1 for the 1×10 -6 The burr part of the amorphous alloy 3 is heated to the glass transition temperature Tg and the melting temperature T within a second of heating time 1 After that, use the electrode 1 as a punch to apply a pressure of 15 MPa to the burr part of the amorphous alloy 3 to remove the burr, and blow nitrogen gas with a pressure of 0.1 Pa to the burr part to achieve the purpose of cooling while removing the burr. Wherein, in the whole process of removing burrs, the crystallization reaction of the amorphous alloy 3 is prevented from taking place based on the TTT diagram. Wherein, the end of the electrode 1 in contact with the burr portion of the amorphous alloy 3 is set as the tip portion 11 , so that the burr can be easily removed....

Embodiment 3

[0044] See figure 1 and Figure 4 . A method for deburring amorphous alloys in this embodiment uses the electrode 1 to release the 10000J electric energy stored in the capacitor 2, and uses the electric energy released by the electrode 1 in a 1×10 -4 The burr part of the amorphous alloy 3 is heated to the glass transition temperature Tg and the melting temperature T within a second of heating time 1 After the interval, use the electrode 1 as a punch to apply a pressure of 30 MPa to the burr of the amorphous alloy 3 to remove the burr. While removing the burr, helium with a pressure of 0.5 Pa is used to blow the burr to achieve the purpose of cooling. Wherein, in the whole process of removing burrs, the crystallization reaction of the amorphous alloy 3 is prevented from taking place based on the TTT diagram. Wherein, the end of the electrode 1 in contact with the burr portion of the amorphous alloy 3 is set as the tip portion 11 , so that the burr can be easily removed.

Abstract

The invention relates to the technical field of surface treatment of amorphous alloys, in particular to a deburring method for an amorphous alloy. Electric energy stored in a capacitor is released through an electrode; the electric energy released by the electrode is used for heating burr positions of the amorphous alloy to a certain temperature within certain heating time to remove burrs; the amorphous alloy is prevented from undergoing a crystallization reaction based on a TTT (Isothermal Transformation) diagram. The heating time for the electrode to release electric energy is 1*10<-6> to 1*10<-3> seconds, so that the deburring method has the advantages of short production time and good deburring effect. Since an inert atmosphere of a certain pressure is blown towards the burr positions during deburring to fulfill the aim of cooling, so that the amorphous alloy can be prevented from undergoing an oxidation reaction and the crystallization reaction.

Description

technical field [0001] The invention relates to the technical field of surface treatment 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 ...
