METHOD FOR TREATING TABLETING SURFACE OF PESTLE OR MORTAR FOR TABLETING TABLETS, PESTLE OR MORTAR THAT HAS BEEN SURFACE TREATED BY THE METHOD, AND TABLETS TABLETED BY THE PESTLE OR MORTAR

摘要

[Issue] Various metals can simply, easily, and efficiently form an alloy together with tableting surfaces of various base metal materials, and can reliably combine with the tableting surfaces. [Means for Solution] 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.
