<p>The invention relates to a protective layer against wear based on artificial resin. Hard particles ( 1 ) having a hardness of at least 6 on the Mohs scale are embedded in said layer, as are compact, round, solid particle ( 2 ), 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 ( 2 ) begins at least with the smallest grain diameter of the hard particles ( 1 ) and reaches a maximum of five times the value of the largest hard particle diameter, the average grain diameter of the solid particles ( 2 ) being larger than the average grain diameter of the hard particles ( 1 ). The hard particles and round solid particles are admixed for producing a protective layer against wear and for providing wear-resistant surfaces.</p> |
