METHOD FOR PRODUCING DECORATIVE METALLIC ARTICLE WITH WOOD-GRAIN METAL PATTERN AND DECORATIVE METALLIC ARTICLE WITH WOOD-GRAIN METAL PATTERN

摘要

Provided are a method for producing a decorative metallic article with a wood grain metal pattern and the decorative metallic article with 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 a copper plate and a silver plate; a multi layering and adhesion step of mutually laminating the copper and silver plates one another by applying water to the surfaces of the plates, and elongating the laminated plates so that a thickness thereof decreases in 10% or more, thereby to adhesively paste together; a wood grain metal plate forming step of forming a wood grain pattern by carving the surface of the multi layered plate produced in the multi layering and adhesion step so as to expose at least a part of the plurality of plate layers, and elongating the surface of the multi layered plate to become flat; a decorative object forming step of forming a decorative object by using the prepared wood grain metal plate; a decorative object drying step of drying the decorative object; and a sinter producing step of sintering the decorative object produced in the decorative object drying step, thereby to obtain the decorative metallic article.
