Abstract

PURPOSE: To obtain a combined material for precious ornament having color patterns excellent in aesthetic characteristic by combining Pt or Pt alloy, Au alloy, and Au-Fe alloy, working the resulting combined material into the prescribed shape, and then carrying out heating in an O2-containing atmosphere.
CONSTITUTION: For example, a metal plate is prepared by using an Au alloy to be a base material, and plural grooves are formed at prescribed spaces in the surface on one side of this metal plate by means of machining. Subsequently, a stock composed of an Au-Fe alloy to be an intermediate layer is prepared. Then, a stock composed of a K12-22Au alloy (containing 50-91.7wt.% Au) to be a coating material is prepared. The base material, the intermediate layer, and the coating material mentioned above are joined by means of hot rolling. The resulting joined material is worked into the prescribed shape and heated up to 200-450°C in an O2-containing atmosphere. By this method, the hue of the Au-Fe alloy as the intermediate layer is changed and color patterns together with the Pt or Pt alloy and the K12-22Au alloy can be allowed to appear, by which the combined material for precious ornament having the above characteristic can be obtained.
