A method for increasing the surface area and roughness of metals, ceramics and composites on a micro-scale, and the surfaces themselves, is disclosed whereby a laser beam having a radiation wavelength of from UV to infrared is pulsed onto the surface of the material. The energy density of the radiation...http://www.google.es/patents/US5473138?utm_source=gb-gplus-sharePatente US5473138 - Method for increasing the surface area of ceramics, metals and composites
