Abstract

PURPOSE: To obtain armoring parts for watch having high hardness and corrosion resistance and also beautiful gloss, by forming the coating layer of an amorphous alloy on the surface of a metallic mold for the armoring parts.
CONSTITUTION: After forming nocrystal alloy on a part or whole surface of mold having the final shape or nerly formed to the final shape of armoring parts for watch by the vacuum surface treatment, said mold is removed and desired parts is obtained. For example, Fe alloy mixed in the ratio of 59 (Fe): 16 (Cr): 10 (Mo): 15 (C) by atomic% and forming an amorphous alloy, is melt casted in the vacuum furnace and a target having a fixed diemension is made. Said target is sputtered on a metallic mold 1 for the case body made of brass previously by the high frequency sputtering apparatus. Sputtering conditions are as follows: 13.56MHz, 5KV, 300mA electric discharge condition; 40mm distance between both electrodes; 5×10-2 Torr. Ar atmosphere; 100Å/mm sputtering speed. 500H sputtering time and 50 pieces molds are put in the same bell jar and desired case body is obtained.
