Abstract
In a method for manufacturing a sliding coating for a composite component, an adhesive layer on the side of the base body, made of a lead- and bismuth-free bronze, is first applied to a solid, iron-based bearing material of a base body by deposition welding. An outer sliding layer made of a lead-free and bismuth-containing bronze is then applied to the adhesive layer by deposition welding.
