Metal coating method and metal-coated material

摘要

Metal coating is performed by dispersing powders of an inorganic compound in a liquid containing an organic solvent and irradiating vibration or applying heat in a state in which a substrate is immersed in the liquid to form a metallic film on the substrate. By this, provided are a novel method which can uniformly coat the metallic film on various types of arbitrary substrates with a thickness on the order of from several nanometers to several thousand nanometers by a simple means without requiring a need for a means having such a multiple of restrictions as in the vacuum system, without caring about generation of a noxious gas or the like, and free from any restriction on a heating temperature or a selection of a material, and a material coated with a metal by this method.
