Abstract

The invention discloses an antifouling titanium alloy material based on a bionic super-smooth surface and a preparation method and application thereof. The preparation method comprises the steps: a titanium alloy substrate is treated through an anodic oxidation method, a nanostructure layer arranged in an array mode is formed on the surface of the titanium alloy substrate, and the nanostructure layer comprises nanopores or nanotubes with different morphologies and / or sizes; chemical modification is carried out on the titanium alloy substrate with the nanostructure layer by using a fluorosilanemodifier; and a lubricant is applied to the surface of the titanium alloy substrate subjected to chemical modification, and the antifouling titanium alloy material based on the bionic super-smooth surface is obtained. The bionic super-smooth surface can obviously reduce the attachment amount of bacteria on the surface of the titanium alloy, has a remarkable antibacterial attachment effect and anexcellent slow release effect, and meanwhile, the preparation method of the bionic super-smooth surface is a green, environment-friendly and efficient antifouling method and has a wider application prospect in the marine antifouling field.

Description

technical field

[0001] The invention relates to an antifouling titanium alloy material, in particular to an antifouling titanium alloy material based on a bionic super-slip surface and a preparation method thereof, and an antifouling method for preparing a bionic super-slip surface on a titanium alloy, which belongs to marine Antifouling coating technology field. Background technique

[0002] Adhesion and deposition of marine organisms on marine equipment can lead to serious biofouling problems, such as pipeline blockage, increased gravity and frictional resistance of ships, and corrosion of marine devices, which cause huge losses to the marine economy. Titanium alloys are widely used in marine environments due to their excellent mechanical properties and corrosion resistance, but due to their good biocompatibility, they face more serious problems of biofouling, which limits their application in marine environments. There are many kinds of antifouling technologies at presen...
