Abstract
An insulating substrate, such as a glass windscreen, is coated with a conductive coating of an oxide of at least one metal by a process in which the substrate is subjected, in a rarefied oxygen atmosphere, to metal ions and oxygen ions arising from bombardment of a metal source with an electron beam and the proximity to the substrate of a negatively biased grid serving to accelerate the metal ions to the substrate where they combine with oxygen to form an oxide coating.
