Abstract
A preparation method for adhesive bonding of magnesium-containing aluminum alloy products includes a magnesium-containing aluminum alloy product including a matrix and a surface oxide layer overlying the matrix. The magnesium-containing aluminum alloy product also includes intermetallic particles at least proximal the surface oxide layer. The method also includes ablating at least some of the intermetallic particles via an energy source, and in the absence of melting of the matrix of the magnesium-containing aluminum alloy product.
