On the purpose of improving the surface wettability and tribological properties of Ti6Al4V alloy for artificial joints, we designed a novel ‘soft (hydrogel layer)–hard (porous Ti6Al4V alloy substrate)’ structure, which was fabricated by laser texturing, surface dopamine modification and poly(vinyl a...
