Abstract

The invention relates to a method for metal surface treatment by nanosecond laser. The method comprises the following steps of grinding the surface of a metal piece, polishing the surface of the treated metal piece by the nanosecond laser to obtain a surface with a micro-nano composite structure, cleaning and blow-drying the surface with the micro-nano composite structure, and treating the blow-dried metal piece with a low surface energy substance solution. The surface of the workpiece is treated by a nanosecond laser device with lower cost and is modified by substances with low surface energy, so that the surface of the workpiece has good superhydrophobic performance; and the method is low in equipment cost and simple in preparation process, is not strict in environmental requirement, andis suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a method for metal surface treatment by nanosecond laser. Background technique [0002] The hydrophobicity of a solid or solution means that water will form a large contact angle on a hydrophobic surface and form a droplet shape, 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 process of hydrophobic processing on the product surface is relatively complicated, and the processing cost is high. How to reduce processing costs, improve work efficiency and ensure better hydrophobicity of the workpiece surface is an urgent problem in this field. Contents of the invention [0004] Based on this, it is necessary to address the above technical problems and provide a method for metal surface treatment by nanosecond laser, which has the ...
