Abstract
The surface of nuclear reactor structural components e.g. fuel cans is rendered corrosion resistant and capable of operating at high temperatures, by depositing on the surface one or more elements from a fine dispersion thereof in a gaseous atmosphere by electrical gas discharge e.g. a glow discharge. The elements specified are Si, C, Cr and Ni and are preferably atomized by cathodic disintegration, and the glow discharge intensity is maintained at a high level, e.g. 0.1 watts per cm.2, whereby the surface is heated, the deposited element diffuses into the surface, and the boundary layer on the surface assumes an ideal form of a regular crystal lattice. The cans may be made of zirconium or alloys thereof, but steel and aluminium may also be treated. A number of elements may be applied in succession, and a final coating of C formed from a carbon halide is preferred. Si may also be deposited from silicon halides. The surface may be connected as cathode for the glow discharge source, and an inert gas may also be present. Preferably the voltage for glow discharge is pulsed, and the surface is pre-cleaned by glow discharge, the ionized gas removing thereby the same amount of material as is subsequently deposited by the coating.
