1. A process for producing an abrasive coating on a substrate, or on a blade tip of a rotor blade, the process comprising:
applying two layers for the abrasive coating, namely a bottom solder layer and an outer, second layer of a coating comprising abrasive particles as tapes, to the substrate, and
joining the bottom solder layer to the substrate by a soldering process, as a result of which the outer, second layer is also bonded-on,
where a material of the bottom solder layer has a melting point which is at least 10K lower than that of a material of the substrate, and also has a melting point which is at least 10K lower than that of a material of the outer, second layer, and
wherein the abrasive particles are present in the outer, second layer and partly in the bottom solder layer.
