Abstract
A powder mixture for thermal spraying is disclosed which comprises at least two powders of alloys with a different hardness in the range from 200 to 650 Hv and/or a different static coefficient of friction in the range from 0.01 to 0.3 .mu.s. The protective layers obtained by thermal spraying of the mixture have a heterogeneous, lamellar structure with low internal tensions even at substantial thickness, they have high resistance to frictional wear and very good frictional properties.
