Laser melting treatment is the use of high energy density of the laser beam to melt the surface of the metal cooling treatment organization, so that the metal surface layer to form a layer of liquid metal cooling organization, due to the heating and cooling of the surface layer is very rapid so the organization obtained is very fine, if the cooling rate through the external medium to achieve high enough, it can inhibit the crystallization process, and the formation of amorphous state, so also known as laser melting an Amorphous treatment, also known as laser glazing.
