It is demonstrated in the paper that epitaxial growth from the crystalline substrate at melt bottom is the most critical factor during laser glazing. The chief condition for glass forming is the abrupt stop of the epitaxial growth during solidification, which is dependent upon the eutectic composition, composition homogeneity, fine microstructure, laser glazing power density and scanning velocity.
