Coating of a body made of steel or CFRP material, in particular a roller, with an applied on the body adhesive layer of thermoplastic material, in the near-surface material matrix solid (powder) particles are positively adherent embedded such that only a portion of these particles from the Adhesive layer protrudes, as well as with the adhesion promoter layer covering functional layer of oxide ceramic and / or low-wear hard metal, in which the protruding from the adhesive layer particle partial areas are embedded. To produce such a coating, the adhesion promoter layer is expediently heated to a honey-like viscosity, and powder particles are injected into the near-surface material matrix of the heated adhesion promoter layer in a form-fitting manner, for example by thermal spraying, so that only the tips of these particles protrude. These tips enter into a connection with subsequently applied powder particles containing the functional layer of oxide ceramics such as Al 2 O 3 , Cr 2 O 3 , TiO 2 , SiO 2 or ZrO 2 or mixtures thereof and / or low-wear hard metal such as WC / Co, Cr 3 C 2 / NiCr, NiCrBSi, WC / Ni, TiC / Ni, molybdenum or chromium or mixtures or alloys thereof. |
