Abstract
An aluminium object is manufactured by means of a process including conversion coating of the aluminium object to chromate, the sequential application of a basecoat to the outside surface and the subsequent application of a basecoat forming the substrate, vacuum metal coating of a metal which has a tendency to corrode the basecoat to form "islands" of metal which are covered over with a transparent resin layer to encapsulate and isolate the islands. These have a thickness of less than one thousand angstroms and a mean diameter of less than three thousand angstroms. The island structure is etched after the metal has accreted as a deposit between the stage of nucleation and that of channelling, forming an electrically conducting film. The etching agent is selected so as to remove the channels from between the islands to improve the adhesion of the upper coating to the dielectric substrate by at least one order of magnitude more than the adhesion to the islands. <IMAGE> STARTING AL PART FORMATION OF THE CONVERSION LAYER ON THE AL PART SPRAY DEPOSITION/HARDENING OF THE BASE LAYER SPRAY DEPOSITION/HARDENING OF THE BASECOAT VACUUM DEPOSITION AND CREATION OF ISLANDS BY ETCHING SPRAY DEPOSITION AND HARDENING OF THE UPPER COATING
