Abstract
Described are methods of treating surfaces of metal alloy substrates and associated metal alloy products. The methods may include providing an aluminum alloy product having a bulk and a surface and scanning abeam of high energy across the surface. The method may further include applying a liquid layer onto the surface prior to scanning a beam of high energy. The beam of high energy may interact with the surface and/or the liquid layer to form a treated surface. The beam of high energy may interact with the surface and/or the liquid layer to physically modify the at least a portion of the aluminum alloy product to form a treated sub-surface layer.
