There is provided a coating for a body of steel or a carbon fiber reinforced plastic material, particularly a roller, with an adhesion-promoting layer of thermoplastic that is deposited on the body, in the surface near material matrix of which solid (powder) particles are embedded in a form-fitting adhering manner such that only a partial region of these particles projects from the adhesion promoting layer, as well as with a functional layer of oxide ceramic or wear-resistant hard metal overlaying the adhesion-promoting layer, in which the partial regions of the particles projecting from the adhesion-promoting layer are embedded. For producing such a coating, the adhesion-promoting layer preferably is heated to a honey-like viscosity, and powder particles are injected, for example by thermal spraying, into the surface near material matrix of the heated adhesion-promoting layer in a form-fitting adhering manner such that only the tips of these particles project. These tips connect to subsequently deposited powder particles which form the functional layer of oxide ceramic such as Al2O3, Cr2O3, TiO2, SiO2 or ZrO2 or mixtures therefrom and/or wear resistant hard metal such as WC/Co, Cr3C2/NiCr, NiCrBSi, WC/Ni, TiC/Ni, molybdenum, or chromium or mixtures or alloys thereof
