Exposure to laser radiation for creation of nanoporous structures in the Cu–Zn alloy was investigated. It was established that exposure to laser pulse-periodic radiation with pulse repetition rate up to 5000 Hz makes it possible to form a nanoporous structure in the near-surface layer. The conditions of increase of area depth of such structures formation up to 40–45 μm were ascertained. The temperature and speed conditions which provide predominant channel-type nanopores formation with width of about 100 nm forming a nanoporous net were determined. This patented technology is a perspective for production of catalysts and microfiltration membranes.
► We realized exposure to laser pulse-periodic radiation on Cu–Zn alloy.
► Zn concentration on the surface was significantly reduced.
► Nanoporous structure was formed in the near-surface layer of the material.
► Structure with channel-type nanopores with width of about 100 nm was formed.
