ABSTRACT:
Method of preparing metallic compound materials for spectacle frames, watch casings, bracelets for watches and others, necklaces, and other decorative articles, which comprise a base made from austenite stainless steel, and an alloy of precious metals of a desired purity such as gold, platinum, and palladium which is selectively or partially laid over said base steel. Said method comprises masking the base steel at its outer surfaces other than those selected parts which shall be laid over by said precious metal alloy, plating said selected parts with a plurality of layers of metals which constitute said precious metal alloy and which are respectively in volumes correspondent to their constituent percentage ratios of said alloy, removing the masking from the base steel, and subjecting the metal layers on the base steel to such temperature for a short period of time which is sufficient to cause them to be in liquid phase, resulting in binding them onto the base steel as a single alloy layer of one or more precious metals of the desired purity, when they are solidified.
