Title (EN) ALLOY AND COMPONENT HAVING A LAYER THEREOF
(FR) ALLIAGE ET ÉLÉMENT AYANT UNE COUCHE DUDIT ALLIAGE
Abstract:
(EN) An iron-based alloy is described. Also described is a component having a surface layer 12 of an iron-based alloy, a method of providing a surface layer of an iron-based alloy on a component, an apparatus arranged to provide a surface layer of an iron-based alloy on a component and use of a surface layer of an iron-based alloy to improve corrosion pitting resistance and/or water droplet erosion (WDE) thereof.
(FR) L'invention concerne un alliage à base de fer. L'invention concerne également : un élément ayant une couche de surface 12 d'alliage à base de fer, un procédé de fourniture d'une couche de surface d'alliage à base de fer sur un élément, un appareil agencé pour fournir une couche de surface d'alliage à base de fer sur un élément et l'utilisation d'une couche de surface d'alliage à base de fer pour améliorer la résistance à la corrosion par piqûres et/ou l'érosion par gouttelettes d'eau (WDE) de ce dernier.
