This paper investigates the wear resistance of NiCr-Fe+50(80)%chromium carbide and NiCr-Fe+50%SiC coatings. This is achieved by the plasma spraying of composite powders and the mechanical mixing of powders, followed by an additional treatment with pulses of a plasma jet. The mechanism of wear of the sprayed coatings is also analyzed. Paper includes a German-language abstract.
