METHOD FOR PRODUCING DECORATIVE METALLIC ARTICLE HAVING WOODGRAIN METAL PATTERN, AND DECORATIVE METALLIC ARTICLE HAVING WOODGRAIN METAL PATTERN

摘要

Provided are a method for producing a decorative metallic article having a wood grain metal pattern and the decorative metallic article having the wood grain metal pattern; the decorative metallic article comprising a sintered copper part produced by sintering a plastic copper containing clay compound, and a sintered silver part produced by sintering a plastic silver containing clay compound. The method comprises: a plate forming step of forming the plastic copper containing clay compound and the plastic silver containing clay compound into plate-like shapes respectively, so as to produce a copperplate and a silver plate; a multi layering and adhesion step of mutually laminating the copper and silver plates one another, and elongating the plates so that a thickness of the laminated plates decreases in 10% or more, thereby to adhesively paste the laminated plates together; a decorative object forming step of forming a multi layered decorative copper-silver object by using the multi layered plate; a multi layered decorative copper-silver object drying step of drying the multi layered decorative copper-silver object; a wood grain metal pattern forming step of cutting or polishing a surface of the dried multi layered decorative copper-silver object to form notches so that the wood grain metal pattern appears on the decorative object; and the sinter producing step of sintering the decorative object on which the notches are formed, thereby to obtain the decorative metallic article (69).
