Abstract: PCT No. PCT/FR95/01576 Sec. 371 Date Oct. 28, 1997 Sec. 102(e) Date Oct. 28, 1997 PCT Filed Nov. 29, 1995 PCT Pub. No. WO96/17105 PCT Pub. Date Jun. 6, 1996Surface preoxidation of the substrate is carried out by bringing the substrate into contact with an oxidizing gas excited by a cold plasma, the substrate being situated in the flowing afterglow of the cold plasma used to excite the oxidizing element and being heated to an oxidation temperature of less than 500 DEG C. A metal oxide is formed at the surface of the preoxidized substrate by heterogeneous oxidation of a metal halide with a gas mixture including an oxidizing element activated by a cold plasma. The oxidizing gas mixture is brought into contact with the halide as directly as possible in the vicinity of the substrate arranged in the far flowing afterglow of the cold plasma. The cold plasma is preferably generated by microwaves. The process can be used in particular for producing a protective coating on a cladding tube of a nuclear fuel rod.
