Abstract
The invention relates to a protective layer against wear based on artificial resin. Hard particles () having a hardness of at least 6 on the Mohs scale are embedded in said layer, as are compact, round, solid particle (), which are essentially free of sharp edges and have a hardness of at least 5 on the Mohs scale. The grain size distribution of the round solid particles () begins at least with the smallest grain diameter of the hard particles () and reaches a maximum of five times the value of the largest hard particle diameter, the average grain diameter of the solid particles () being larger than the average grain diameter of the hard particles (). The hard particles and round solid particles are admixed for producing a protective layer against wear and for providing wear-resistant surfaces.
