    Abstract: A method for tableting surface treatment of a tableting punch or die includes provisional filming and beam irradiation steps. In the provisional filming step, a tableting surface of a base metal material 1 is subjected to shot peening using different type metal grains 2 made of a different type of metal for adhesion, or the different type metal grains 2 are adhered by a binder whereby forming a different type metal film 3 on the surface. In the beam irradiation step, after the different type metal film 3 is formed, the surface is irradiated with an electron beam 4 or laser beam as energy beam to combine the different type metal film 3 and the base metal material 1.
