Abstract

The invention provides a preparation method for a zirconium-based amorphous alloy. The preparation method comprises the following steps that 1 one end of a basis material is fixedly connected to the side wall of a reactor, the other end of the basis material is rotatably hung in the reactor, and a cooling medium is pumped into the reactor; 2 zirconium-based mixed fine powders are sent to the upper surface of the basis material through a powder-sending control device at a constant speed, and the fine powders are located under a laser processing head of an optical maser; 3 the optical maser is started, the laser processing head is connected with a gas protecting device, laser is ejected from the laser processing head, the laser is pointed on the upper surface of the basis material point-by point, the optical maser is closed at interval, and amorphous points are formed; 4 the basis material is rotated at a constant speed, so that the solidified amorphous points can be immersed into the cooling medium to conduct the post cooling treatment; the step is repeated, and the zirconium-based amorphous alloy is formed on the upper surface of the basis material. The preparation method for the zirconium-based amorphous alloy has the advantages that the forming ability of the amorphous alloy is high, and the operation is simple and accurate; the preparation method is an ideal method for the preparation of the zirconium-based amorphous alloy.

Description

technical field [0001] The invention belongs to the technical field of amorphous alloy preparation and relates to a preparation method of zirconium-based amorphous alloy. 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] Although the research and development of amorphous alloys has achieved quite remarkable achievements, from scratch, from small to large. However, compared with traditional metal crystal materials, the three-dimensional size of amorphous alloys is limited, and can only be made into very ...
