This study investigates the use of a CuBr vapor nanosecond laser with a 510 nm/578. 2 nm wavelength for the surface treatment of 1050 aluminum and 2219 aluminum alloys. Laser-induced periodic surface structuring was used to optimize processing parameters to achieve hydrophobic and hydrophilic properties on the surface. https://chefesquipmenters.shop/product-category/egg-rings/
