<p>The invention relates to a protective layer against wear based on artificial resin according to figure 2. Hard particles (1) having a hardness of at least 6 on the Mohs scale are embedded in said layer, as are compact, round, solid particles (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 invention also relates to a mixture of hard particles and round solid particles for producing a protective layer against wear, a method for producing a protective layer against wear, and the use of one such layer for producing wear-resistant surfaces.</p> |
