Abstract: A surprisingly corrosion and abuse resistant plastic object vacuum-metallized with a corrosion prone metal, namely indium, on a dielectric substrate consists of minute specular electrically-discrete "islands" of the indium topcoated with a clear resinous layer which encapsulates and insulates the islands, one from another. The indium islands are less than one thousand angstroms thick and have an average diameter of less than three thousand angstroms. This island structure is secured by stopping the growth of the metal as it is deposited between the nucleation stage and the stage of channelization or formation of an electrically conductive film. The island structure permits the dielectric resinous topcoat to penetrate in, about and under the metal islands encapsulating and securely bonding them to the substrate.The vacuum deposited indium gives a bright sheeny appearance which, when properly topcoated, very closely duplicates the appearance of electrodeposited chrome.
