Development of method for creating nanoporous metallic materials with through pores during laser irradiation

The method of nanoporous materials creation, consisting of creation necking zones on a sheet blank surface, blank etching, carrying out of electrolytic deposition of material layers with closed pores formation, is developed. Formation of nanodimensional through pores carry out by the subsequent power action with high impulse frequency with by one of alloy components sublimation. At laser action in electrodeposited brass nanoporous structure is formed. The average size of such pores is about 40…60 nm. Received nanoporous metal material with through nanodimensional channels has prospects of application for ultrafiltration membranes and catalysts.
