Laser functionalization of surfaces

The treatment of surfaces by physical or chemical methods is a very usual way to change their original properties. Although the most common use of a surface functionalization is for tribology aims, modifications of the topography that leads to changes in the surface roughness, its hydrophilicity or hydrophobicity, its light scattering behavior, biocompatibility or even aesthetic changes are possible. In this field, laser sources have proven to be a most versatile and useful tool, being a clean and fast way to achieve any of those objectives. In this work we show the results of functionalization by laser texturing of four different materials
