Abstract EN
Tungsten carbide-cobalt powders (WC-17wt% Co) were plasma sprayed by a water-stabilized system WSP.
Experiments with variable feeding distances and spray distances were carried out.
Thinner coatings were deposited on carbon steel substrates and thicker coatings on stainless steel substrates to compare different 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 resistance 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 parameters onto coating wear performance was observed.
The results of mechanical tests were discussed in connection with changes of phase composition and with the quality of the coating's microstructure.
The results show that for obtaining the best possible WC-17Co coating with WSP process, from the viewpoint of wear resistance, the desired parameters combination is long feeding distance combined with short spray distance.
