[0034] figure 1 It is a schematic flowchart of a method for metal surface treatment by femtosecond laser in one embodiment. Include the following steps:

[0035] S100, grinding the surface of the metal piece.

[0036] The purpose of the grinding treatment is to remove the oxide layer and impurities on the metal surface, exposing the inner metal with bright color. For example, sandpaper can be used to sand and polish metal surfaces. Rough sanding with large-grained sand...

Abstract

The invention relates to a method for metal surface treatment through femtosecond laser. The method for metal surface treatment through the femtosecond laser comprises the following steps that polishing treatment is carried out on the surface of a metal piece; the femtosecond laser is used for machining the polished metal piece surface so that a surface with a micro-nano composite structure can beobtained; the surface with the micro-nano composite structure is washed and blow-dried; and the blow-dried metal piece is put at the room-temperature environment for a period of time. According to the method, complex following surface machining treatment procedures are not needed, the metal piece only needs to be kept at the room temperature for a period of time, an excellent surface hydrophobiceffect can be achieved, the process is simple, the machining efficiency is high, and the surface hydrophobic performance of the workpiece is good.

Description

technical field [0001] The present invention relates to the technical field of laser processing, in particular to a method for metal surface treatment by femtosecond laser. Background technique [0002] The hydrophobicity of a solid or solution means that when water is on a hydrophobic surface, it will form a large contact angle to form a droplet, making it difficult for water to adhere to the surface. When the surface of the product is hydrophobic, it is difficult to attach dust and has a self-cleaning effect. [0003] At present, the hydrophobic processing on the surface of the product has the problems of complicated process, the preparation process affects the original functional properties of the product, the surface modification and post-treatment are required, the chemical waste liquid required for the preparation needs specific recycling treatment, and the hydrophobic durability is poor. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary to provide a ...
