A process for forming a coating on a substrate, including the steps of effecting tribostatic charging of a body of powder by establishing a fluidis ed- bed of the body of powder in a fluidising chamber at least a part of which i s conductive, applying a voltage to the conductive part of the fluidising chamber, immersing a substrate which is electrically non-conductive or poorl y conductive, either electrically isolated or earthed, wholly or partly in the fluidised bed, withdrawing the substrate from the fluidised-bed and forming adherent particles of the powder into a continuous coating over at least par t of the substrate.
