Paper Abstract

This paper reports rapidly solidified amorphous by 10 kW cw CO2 laser glazing Fe40Ni36Cr2Si8B14 and Fe40Ni40P16B4 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.
