Embodiment

[0034] Taking a typical zirconium-based amorphous alloy (Zr41.2Ti13.8Cu12.5Ni10Be22.5) as an example, the laser nitrided surface was prepared in a nitrogen atmosphere, and then the nitrided surface was laser polished, and the following examples were used for further comparison The implementation process and beneficial effects of the present invention are described.

[0035] figure 2 When the average laser power is 7.12-8.82W, the scanning speed is 100-500mm / s, the overlapping rate of adjacent scanning lines is 80-90%, and the scanning is repeated once, after rough laser polishing is performed on the surface of the laser zirconium nitride-based amorphous alloy , the surface roughness value obtained by laser confocal, it can be seen that after rough laser polishing in a nitrogen atmosphere, the surface roughness is reduced by a maximum of 0.905 μm compared with the laser nitrided surface, which is 86.3%, indicating that the laser roughness in a nitrogen atmosphere Polishing ca...

Abstract

The invention relates to a method for realizing laser zirconium nitride-based amorphous alloy surface planarization through laser polishing, and belongs to the technical field of amorphous alloy surface modification. The surface of a laser zirconium nitride-based amorphous alloy is subjected to laser polishing in a nitrogen atmosphere by utilizing heat generated by focusing laser on the surface of a material, so that the surface is re-melted, and the surface roughness is reduced. The method effectively solves the problem of poor surface quality of the existing laser zirconium nitride-based amorphous alloy. The surface roughness of the laser zirconium nitride-based amorphous alloy is regulated and controlled by changing laser polishing parameters. The method is simple in implementation process, high in efficiency and high in practicability, and can be applied to reducing the surface roughness of the laser zirconium nitride-based amorphous alloy and enhancing the practical application of the laser zirconium nitride-based amorphous alloy.

Description

technical field [0001] The invention relates to the technical field of surface modification of amorphous alloys, in particular to a method for realizing planarization of the surface of a laser zirconium nitride-based amorphous alloy by laser polishing. It can be applied to reduce the surface roughness of the laser zirconium nitride-based amorphous alloy, and enhance the practical applicability. Background technique [0002] The large cooling rate of metal elements in the liquid phase makes amorphous alloys have no crystal atomic structure, no grain boundaries and dislocation defects, so amorphous alloys have excellent properties, such as high strength, high elasticity, and strong corrosion resistance. These characteristics make amorphous alloys have potential applications in aerospace, precision machinery, military weapons and other fields. However, amorphous alloys are prone to highly localized shear band deformation under tensile loading, which limits their practical appl...
