It has been a hot topic in the field of vehicle research to find a new anti-pollution and anti-drag means used for vehicle surface. In recent years

the traditional organic tin antifouling coatings are being eliminated. Titanium alloy has the advantages of low density

high strength

heat resistance and corrosion resistance

etc.

and is widely used in the structure of vehicle shell and blade. Therefore

the realization of surface microtexture drag reduction on titanium alloy has a wide application prospect and important research significance. In this paper

the surface microtexture was obtained on the surface of TC4 titanium alloy by nano laser machine. The structure was characterized by optical microscopy and laser focusing observation. The experimental results show that the non-smooth surface with continuous structure can reduce the frictional resistance of fluid compared with smooth surface. In order to obtain the electrochemical parameters of surface texture under seawater condition

the corrosion and wear experiments of TC4 titanium alloy disk marked with surface microtexture were carried out by electrochemical friction testing machine. The results show that suitable surface microtexture can significantly reduce the friction coefficient

friction resistance and wear corrosion potential of titanium alloy materials

and improve the corrosion resistance and working life of the vehicle structure in the marine environment.
