摘要： Methods are provided for repairing a worn surface of a steel die-cast die. The method includes heating an amorphous material to a predetermined temperature with a laser beam and allowing the melted amorphous material to solidify to thereby form an amorphous layer over the worn surface. These processes are useful for eliminating or minimizing cracking and/or part distortion and minimize heat-affected zone during welding. In addition, the formation of an amorphous layer over the worn surface allows the repaired die-cast die to better withstand typical operating environments than previous repair materials. These methods combine low heat input welding with amorphous alloys to effectively repair die-cast dies.
