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

摘要

The fabrication of titanium (Ti) porous structures covered with periodic nanostructures from mi-cro Ti powders by femtosecond laser-induced sintering and simultaneous laser-induced periodic sur-face structures (LIPSS) are demonstrated. Different types of structures are obtained only by control-ling the laser power of a femtosecond laser at wavelength 800 nm: sintered structures and sin-tered/melted structures with periodic nanostructures of period 550~650 nm.
