Abstract:
Intensification’s expedients for nanoporous structures formation in metal materials by selective laser sublimation of alloy’s components are researched. Processing of copper-zinc alloy L62 specimens by laser action with high impulse frequency is spent. Processing is spent in vacuum, the external stretching pressure have been enclosed to specimens with a surface received by mechanical polishing. The nanoporous structure with thickness up to 0.1 mm in brass L62 is formed as a result of laser action in vacuum. Pores are regularly distributed in the subgrain and sufficiently stable in sizes and form. Channel-type nanopores with width ~ 100 nanometers are formed on the border of subgrains, forming a porous network.

Key words:
intensification, nanoporous structure, metal material, laser action, selective sublimation.
