Abstract
The invention relates to a method for coating a mechanically highly loaded surface (2) of a component (1) consisting of a hardened steel with a nitrogen and/or carbon component with an adherent or functional coating (4) for surface treatment, wherein a metallic binding material (5) is introduced into the surface (2) prior to the application of the adherent or functional coating (4) to create a graduated diffusion barrier zone (3) conforming to the surface with a proportion of metal nitride and/or metal carbide increasing towards the surface (2).
Claims11
A process for coating a mechanically highly stressed surface (2) of a component (1) comprising a hardened steel having a proportion of nitrogen and/or carbon with a bonding layer or functional layer (4) for surface upgrading, characterized in that a metallic binder material (5) is introduced into the surface (2) in order to create a gradated diffusion barrier zone (3) which conforms to the surface and has a proportion of metal nitride and/or metal carbide which increases in the direction of the surface (2) before application of the bonding layer or functional layer (4).
