ABSTRACT:
A process is disclosed for the manufacture of semi-finished polychrome composites from thin gage metals by pressing at least one first thin gage metal to create obverse and reverse sockets, then punching first and second inlays from at least one second metal having a gage equal to the depth of such sockets; before the inlays are located in their respective sockets and made fast, the surfaces to be brought into contact are roughened by micromachining, and the components are immersed in a chemical solution of antioxidant and volatile medium; a final step of the process, preferably, would consist in superfinishing the surfaces. A thin gage semi-finished composite articles both faces of which exhibit a polychrome design is obtained.
