Název v původním jazyce

Plasma spraying of tungsten carbide ? cobalt coatings by the water-stabilized system WSP

Popis výsledku v původním jazyce

Tungsten carbide ? cobalt powders (WC-17wt.%Co) were plasma sprayed by a water-stabilized system WSP. A matrix of experiments with variable feeding distances and spray distances was carried out. Thinner coatings were carried out on carbon steel substrates and thicker coatings on stainless steel substrates to compare fast cooling conditions ? the former with slower cooling conditions. Basic characterization of coatings was done by XRD, SEM and light microscopy plus image analysis. Microhardness was measured on polished cross sections. The main focus of investigation was on resistances against wear in dry as well as wet conditions. The appropriate tests were performed with set-ups based on ASTM G65 and G75, respectively. The influence of spray parametersonto coating wear performance was observed. The results of mechanical tests are discussed in connection with changes of phase composition and with the character of the coating?s microstructure.
