Abstract

PURPOSE: To provide colored super hard exterior parts for watch which has hardness equal to that of super hard alloy, various kinds of color tone, and specular gloss, by use of a sintered alloy composed principally of solid solution powder of intermetallic compound WC-ZrN with addn. of Fe, Ni, Co etc.
CONSTITUTION: Solid solution powder of WC-ZrN made at an optional ratio is mixed with a binder for metallic powder, it is then pressure formed and sintered to produce colored, superhard exterior parts for watch. As the binder are used Fe, Ni, Co, Cr, Mo, Si, Ta, Ti, Zr, Mn, Ag, Cu etc. in an amount of 1W50%.
