Four different set-ups equipped with plasma torches namely: (i) SG-100, (ii) Triplex, (iii) Axial III and (iv) h-WSP were used. The spray process parameters were optimized for each torch separately. The zirconia coatings were produced using three different precursors based on: (i) YSZ – yttria partially-stabilized zirconia, (ii) Tosoh-YSZ – yttria fully-stabilized zirconia and (iii) YCeSZ – both yttria and ceria stabilized zirconia powders. Moreover three different concentrations of suspensions were tested for each plasma torch in order to observe their influence on the coating morphology and plasma spray process efficiency. The coatings’ microstructure was observed using light microscopy, scanning electron microscopy (SEM) as well as electron backscatter diffraction (EBSD). Afterwards the phase composition of coatings was analyzed using X-ray diffraction method. The studies showed that the spray process conditions highly influence coatings microstructure and coatings build-up mechanism.
