Application of radiation focusators for creation of nanoporous metal materials with high specific surface area by laser action

Nanoporous metal material with high specific surface area was created under the action of laser radiation with the use of radiation focusators. The regimes of laser action under which nanoporous layer is formed in the centre of the thermal-affected zone on the surface of the material being investigated containing the products of reaction of cuprum and zinc in the alloy with the oxidizing medium. After laser treatment samples of brass L62 were exposed to plastic deformation and high temperature impact for the estimation of mechanical strength and heat resistance of the produced nanoporous material. Main part of the surface does not have destructions after the plastic deformation in two different modes and two high-temperature annealings, exfoliation of the porous layer was not observed, that is the evidence of sufficiently high mechanical strength and high resistance of the derived nanoporous material.
