Abstract: By scanning electron microscopy, the features of the morphology of the crater surface of polycrystalline silumin obtained in distilled water during pulsed laser treatment in the mode of double pulses were established (the energy invested varied from 900 to 1800 J, the exposure time from 15 to 30 min.). It was found that the crater surface varies from characteristic grooves with an energy of 900 J to rarely located deep micro-holes with a diameter of 0.1 to 1 microns. A significant increase in oxygen in the crater structure may be due to the oxidation of the crater surface in an aqueous medium under powerful laser exposure.
