Abstract

Un composant revêtu comprend un corps métallique définissant un volume interne configuré pour y retenir un fluide. Le corps métallique comprend une pluralité de segments, au moins un joint de soudure fixant la pluralité de segments, une surface externe et une surface interne faisant face et définissant le volume interne. Le composant comprend en outre un revêtement protecteur sans chrome disposé sur chacune de la surface externe et de la surface interne. Le revêtement comprend une couche d’époxy et une couche d’oxyde disposée entre la couche d’époxy et la surface externe et la surface interne respectives. Fig. 5
