This paper reports rapidly solidified amorphous by 10 kW cw CO 2 laser glazing Fe 40 Ni 36 Cr 2 Si 8 B 14 and Fe 40 Ni 40 P 16 B 4 alloys, previously prepared by melting the above alloys onto mild carbon steel substrates in a vacuum furnace. The process variables of laser glazing were investigated. The surface layers of laser glazing have been examined by scanning electron microscope (SEM), transmission electron microscope (TEM), and x-ray diffraction (XRD). An amorphization layer was achieved by laser glazing. A large-area amorphous layer has also been obtained by laser overlapping glazing, but a recrystallization was produced in the overlapped area.
