The titanium plates were irradiated with plasma in stationary helium discharges in the PLM plasma device. The duration of discharges in the PLM installation reached 200 minutes. The thermal load on the surface of the test plates is more than 1 MW / m2. The heating temperature of the plates reached 700-900 °C. Scanning electron microscopy of the samples revealed a highly porous stochastic nanostructured surface with dimensions of structural elements less than 500 nm. Such novel material is of interest for nuclear, chemical, hypersonic technologies, as well for biotechnologies and biomedical applications.
