Method of producing clad metals.

摘要

A clad metal is produced by forming a layer of a dissimilar metal powder (2) on the surface of a base metal (1) by cold fixing the powder to the surface under pressure, densing only the surface and a subsurface area of the layer of the dissimilar metal powder by melting and immediately solidifying in a vacuum, compressing the layer of the dissimilar metal powder together with the base metal at a temperature not higher than the solidus-line temperature of the two dissimilar metals under a pressure of not lower than 300 kgf/cm<2> (or 29.4 MPa) using a hot isostatic press, and hot working the layer of the dissimilar metal powder together with the base metal.
