Изменение смачивающих свойств металлов после их обработки лазерным излучением

Abstract

The influence of pulsed laser radiation on the surface texture of an aluminum alloy AMG-6 was experimentally investigated. The diameters of the craters formed in the zone of the beam effect are determined. The dependence of the diameter on the power of the laser beam, the frequency of the pulses and the time of action is established. The process of creating a superhydrophobic coating was investigated. The substrate after the texturing is processed by low-temperature annealing in the furnace for 6 hours at a temperature of 100 °C. The contact angle of the drop of water increased from 90 degrees (polished substrate) to 175 degrees (textured by pulsed nanosecond radiation and processed by low-temperature annealing).
