Beschreibung
Zusammenfassung:	The manufacturing method is intended for the manufacture of a nuclear fuel rod cladding (4) comprising a substrate (14) covered with a protective coating (16). The manufacturing method comprises providing the substrate (14) and applying the protective coating (16) to the substrate (14) by physical vapour deposition by sputtering, simultaneously employing two or more mutually different techniques of physical vapour deposition by sputtering. Le procédé de fabrication est prévu pour la fabrication d'une gaine (4) de crayon de combustible nucléaire comprenant un substrat (14) recouvert d'un revêtement de protection (16). Le procédé de fabrication comprend la fourniture du substrat (14) et le dépôt du revêtement de protection (16) sur le substrat (14) par dépôt physique en phase vapeur par pulvérisation cathodique, en mettant en oeuvre simultanément plusieurs techniques de dépôt physique en phase vapeur par pulvérisation cathodique, différentes les unes des autres.
