Influence of laser radiation for creation of the metallic materials nanoporous structures

We have realized the laser treatment modes that can be used in order to form nanoporous structures in Cu-Zn system alloy. The influence to periodic laser pulses with the pulse-repetition rate up to (4-5)∙103 Hz - provided that the material is being heated below the melting point - makes it possible to produce a steady stress on the sample surface. The proposed patented technology is promising for manufacture of catalysts and ultrafiltration membranes.
