Feasibility of suspension spraying of yttria-stabilized zirconia with water-stabilized plasma torch
Original language description
Thermal spraying of suspensions allows preparation of coatings from submicron-sized powders but demands a source of heat with a high enthalpy in order to provide an appropriate thermal treatment of the liquid feedstock during the in-flight stage so thatthe solvent may be evaporated, dispersed partides melted and accelerated towards the substrate to form a coating. Water-stabilized plasma (WSP) torch developed at the Institute of Plasma Physics AS CR, v.v.i. provides such a heat source with high enthalpy, high velocity of the plasma and, when compared to high-enthalpy gas-stabilized plasma (GSP) torches, relatively cheap operation. In this study, results of our experiments with suspension spraying of yttria-stabilized zirconia (YSZ) with WSP torch arepresented and demonstrate that coating deposition with a high feed rate is possible with WSP technology. Formation of both columnar "cauliflower" microstructure and segmentation cracks was achieved. Variation of the deposition conditions
