Method for manufacturing of Ce-based amorphous alloy micro gear through thermoplastic extrusion

The invention discloses a method for manufacturing of a Ce-based amorphous alloy micro gear through thermoplastic extrusion. The method is characterized in that the Ce-based amorphous alloy micro gear is obtained by enabling the Ce-based amorphous alloy to be subjected to thermoplastic extrusion with a load of 18 N at 140 DEG C. The Ce-based amorphous alloy used by the invention has a lower glass-transition temperature Tg, and can produce plastic deformation at a lower temperature, so that the heat resistance requirement on a processing device is lowered; only a small load (18 N) needs to be exerted during extrusion, which is much smaller (at least 4 orders of magnitudes) than the load required in the traditional forging method; the restrictions of tooth generation on gear size and number of teeth are broken through, and great convenience is provided for industrial production.
