Title: Fabrication of surface texture on Ti6Al4V alloy and its wettability
Abstract: Surface texture of line texture,grid texture and space-lattice was manufactured to Ti6Al4V alloy with laser surface modification method and self-assembled monolayers(SAMs) was deposited on the texturing surface with self-assembled method.Scanning electron microscope,surface profiler and contact angle measurement were used to analyze the surface properties of specimen.It is shown that after laser manufacturing and preparing self-assembled monolayers,the contact angles of the water droplet on the surface increased significantly,and the contact angles of the water droplet on the specimens with line texture can attain to 124.8°,on the specimens with grid texture can attain to 126.1°,on the specimens with space-lattice can attain to 151.6°.The contact angle bears directly upon the surface roughness.The contact angle tends to bigger as the increment of the surface roughness.When the roughness is over 4μm,all of the contact angles are bigger than 150°,it means that a super-hydrophobic surface has formed.
