Abstract

The invention belongs to the technical field of preparation of metal-based microstructural functional surfaces. A method for preparing an aluminum alloy super-hydrophobic functional surface by a laser marking machine comprises the following steps: (1) grinding, ultrasonically cleaning and drying an aluminum alloy sample to obtain a clean aluminum alloy sample; (2) performing laser micromachining: performing laser surface scanning treatment on the surface of the sample by adopting an infrared laser marking machine; and (3) performing silanization treatment: performing ultrasonic cleaning on the sample subjected to the laser micromachining, placing the cleaned sample into an ethyl alcohol solution of cetyl trimethyl silane for soaking to form a layer of hydrophobic film on the surface of the sample, and flushing and drying the sample to obtain a product. The product has the characteristics that (1) preparation can be realized under an atmospheric environment by adopting a method for combining the laser micromachining technology and the silanization treatment technology; (2) the machining cost of the method disclosed by the invention is lower than that of a femtosecond laser device, and machining parameters are independently controllable; and (3) the obtained product is of a structure with a rough surface, and the contact angle for water is about 150 degrees.

Description

technical field [0001] The invention belongs to the technical field of metal-based microstructure functional surface preparation, and in particular relates to a method for preparing an aluminum alloy superhydrophobic functional surface by a laser marking machine. Background technique [0002] Aluminum and its alloys are very important engineering metal materials. Because of their light weight, high specific strength, easy processing and excellent corrosion resistance, they are widely used in automobiles, ships, construction, aerospace and machinery manufacturing, etc. industrial field. However, for the marine transportation industry, ships and other marine transportation tools have been working in harsh seawater media and marine environments for a long time. Due to the presence of reducing ions such as chloride ions, it is easy to cause passivation instability of aluminum and its alloys in seawater. , so that the corrosion resistance of the material is reduced; at the same ...
