Abstract

Abstract Translated from French L'invention concerne le dépôt d'une couche de revêtement à base de chrome sur une pièce de support. The invention relates to the deposition of a coating layer based on chromium on a support piece. Par pulvérisation cathodique en ambiance réactive, on dépose une couche d'une solution solide de chrome et d'un élément tel que l'azote, le carbone, le phosphore, le bore, ou le silicium. La teneur en l'élément ci-dessus est supérieure à la limite de saturation de sa solution solide dans le chrome. Elle est comprise entre T m = 0,2%, et T M = 3% en poids pour le carbone. By cathodic sputtering in a reactive atmosphere, a layer of a solid solution of chromium and an element such as nitrogen, carbon, phosphorus, boron or silicon is deposited. The content of the above element is above the saturation limit of its solid solution in chromium. It is between T m = 0.2%, and T M = 3% by weight for carbon. Application: couche de chrome à haute dureté, résistant à l'usure, à la déformation, à la fatigue et à la corrosion. Application: high hardness chrome layer, resistant to wear, deformation, fatigue and corrosion.
