This paper examines HVOF-sprayed Al2O3-SiC layer systems of differing compositions. The coatings are characterized based on SEM, EDX, and XRD analysis, fracture toughness measurements, and tribological testing. The influence of SiC on mechanical properties is also assessed and a comparison is made with standard alumina coatings. Paper text in German.
