Abstract: Wettability could improve the surface properties of materials, such as anti-friction, wear resistance, anti-icing, etc. Titanium and titanium alloys were widely used in medicine, aerospace, and other fields. Titanium surfaces with water contact angles of 0 degrees, 60 degrees, 120 degrees, and 160 degrees were prepared here using the method of laser processing combined with heat treatment and hot water immersion. It was found that the superhydrophobic surface with micro-nano structures had the smallest coefficient of friction, which was reduced by 22.94% from 0.37418 to 0.28833 with the unprocessed one. The superhydrophilic surface with a micro-nano structure had the smallest wear mass, which was reduced by 96.84% from 0.95 mg to 0.03 mg with the unprocessed one. This paper provided theoretical and experimental support for the effect of surface structure and wettability on friction and wear properties.
