Abstract
A method of coating an inner face of a metal tube with an electrically conducting coating material includes the steps of positioning a wire, made of the coating material, generally axially in an interior of the tube, along the inner face thereof; and passing an electric current pulse of sufficient intensity through the wire to cause an explosive vaporization thereof, whereby particles of the vaporized material impinge on the inner face of the metal tube and form a layer thereon.
