<p>A method of applying an adherent ceramic coating to a metallic workpiece is proposed in which the workpiece is heated above 500 DEG C and the coating directly plasma sprayed thereon before the workpiece has formed any considerable oxide skin thereon. In this way the use of the conventional bond coat is avoided, while the amount of tensile temperature is reduced by the pre-stressing effect thus induced.</p> |
