[0005] 2. Lack of amorphous alloys with good repeatability in production
For a long time, amorphous alloys have been unable to achieve the docking of laboratory conditions and production conditions, that is, the quality of amorphous alloys obtained under laboratory conditions is unstable in production conditions, the repeatability is not good, and the obtained products are not completely amorphous. , cannot be mass-produced
[0006] 3. Amorphous alloys have many excellent mechanical properties, such as high hardness, high strength, and good corrosion resistance, but at the same time, amorphous alloys also have poor plasticity and toughness, and are prone to brittle fractures when used as structural parts. These Disadvantages have restricted the use of amorphous alloy components

Abstract

The invention discloses a method for preparing zr-based amorphous alloy with a coating. The zr-based amorphous alloy is prepared from alloy (Zr1-xAlx)1-a-b-cCuaPrNic according to the atom ratio, wherein x ranges from 0.25 to 0.35, a ranges from 0.12 to 0.17, b ranges from 0.03 to 0.04, and c ranges from 0.05-0.08. According to the prepared zr-based amorphous alloy product, by selectively optimizing the ratio of raw materials, the alloy forming capacity is improved, a base body is coated with the ZrC coating, and accordingly the product has extremely high toughness.

Description

technical field [0001] The invention relates to the field of alloy material manufacture, in particular to a method for preparing a zirconium-based amorphous alloy with a coating. Background technique [0002] Amorphous alloys have more excellent mechanical properties, physical and chemical properties, ultra-high wear resistance and corrosion resistance, and good processing performance than crystalline alloys of the same or similar composition. These excellent properties make amorphous alloys show great application value in the field of functional materials and structural materials, and at the same time make amorphous alloys as a new type of material gradually become a hot spot of attention. [0003] At present, the application of amorphous alloys in the world is mainly concentrated in the application of strips and transformer cores, and there are few examples of the application of bulk amorphous alloys. This is mainly due to the following reasons: [0004] 1. Lack of good a...
