Method for Nano-Structuring Metal Surfaces by Femto-Second Laser Machining
This is a process using a femto-second laser, which produces nanostructures with high surface area on metals such as Ti, Pt, Au, Cu, Al, W. The method can dramatically alter the surface reflectivity rendering the metals black, or can be controlled to produce unexpected colors. For example, platinum and aluminum can be made to appear gold, gray, or black.Applications:The...
