Many products for use in nuclear power stations have to meet strict requirements in terms of in-service corrosion resistance. This is why a large quantity of components are manufactured from austenitic stainless steels. Some of these, which undergo particularly heavy mechanical loadings, also require good wear and seizure resistance. A constant level of corrosion resistance and high wear resistance are two requirements that are difficult to reconcile when using classical processes. Three kinds of austenitic stainless steel components are treated : control rod clusters, for protection against wear ( thin walled tubes 0.4- 1.0mm, with an outer diameter 9.70 mm and overall length 3.8-4.4 m), used in their thousands ;in-core instrumentation flux thimbles, for protection against wear and for promoting good sliding behaviour (diameter ∼8 mm, length ∼40 m), used in their hundreds: fuel assembly socket head screws, for avoiding seizure during assembly (diameter ∼20mm. length ∼50mm), used in there tens of thousands. The processes used on an industrial scale involve the doping of the surface of the components by nitrogen species present in cold plasmas. The latter are produced either by glow discharge or microwave technologies. For each component, the present article details the relevant technologies used an an industrial scale, the metallurgical results (structure, thickness), as well as the mechanical characteristics and corrosion behaviour and possible applications to other industrial fields.
