Fabrication of Porous Ti Structures with Nanostructures from Ti Powders by Femtosecond Laser Pulses

Abstract

The fabrication of titanium (Ti) porous structures covered with periodic nanostructures from micro Ti powders by femtosecond laser-induced sintering and simultaneous laser-induced periodic surface structures (LIPSS) are demonstrated. Different types of structures are obtained only by controlling the laser power of a femtosecond laser at wavelength 800 nm: sintered structures and sintered/melted structures with periodic nanostructures of period 550 similar to 650 nm.
