Preparation method of hydrophobic and oleophobic titanium alloy plate with laser processing skeleton strengthening structure

Abstract

The invention provides a preparation method of a hydrophobic and oleophobic titanium alloy plate with a laser processing skeleton strengthening structure, which is characterized by comprising the following steps of: coarsening the surface of a titanium alloy plate by adopting laser, processing a skeleton structure with a grid-shaped space on the surface of the titanium alloy plate subjected to laser coarsening by adopting laser, and arranging a cladding layer with a micro-nano structure in the grid-shaped space, the hydrophobic and oleophobic performance of the titanium alloy surface is achieved through fluorosilane modification; and the framework structure and the grid-shaped space form a step, and a wear-resistant cladding layer is arranged on the framework structure, so that wear allowance is reserved, the hardness of the surface of the titanium alloy plate is enhanced, and the mechanical performance of the surface of the titanium alloy is achieved. According to the preparation method of the hydrophobic and oleophobic titanium alloy plate with the laser processing skeleton strengthening structure, the hydrophobic and oleophobic performance and the mechanical performance of the titanium alloy surface can be considered, and the defects that the mechanical performance of the titanium alloy surface treated through an existing method is poor and scraping resistance is not achieved are overcome.

Description

Technical field [0001] The present invention relates to the field of titanium alloy material process technology, more particularly, to a laser processing skeleton reinforced structure of the hydrophobic oleophobic titanium alloy plate preparation method. Background [0002] Titanium alloy is widely used in the structural parts of offshore equipment with its low density, high specific strength and corrosion resistance. Due to the high chemical affinity of titanium and its surface oxide film, it is easier to infiltrate and adsorb some marine organisms and oil pollution, so it is necessary to treat the surface of titanium alloy as hydrophobic and oleophobic. [0003] At present, the oxygen-containing micro-nano structure is prepared on the surface of the titanium alloy by means such as anodizing and laser roughing, and then the fluorosilane solution is impregnated on it and dried to obtain a hydrophobic surface. However, the mechanical properties of this surface are poor and it is n...
