Abstract

Wear-resistant hard material layers are prepared on a metal support by applying onto said support a mixture of hard material particles, solder particles and organic binding agents and thereafter soldering the layer by heating. The mixture thus obtained can be applied by means of immersing, screen printing, brushing, spraying or spreading. The stable suspension required for the above steps is prepared by homogeneously grinding the particles together to a particle size from 1 to 20 .mu.m and adding an organic solvent to the binding agent.
