摘要：

Perovskite-type SrZrO(3) has been investigated as a candidate material for thermal barrier coating application. During plasma spraying of SrZrO(3), SrO volatilized more than ZrO(2) and the coating composition deviates from initial stoichiometry. In this investigation, partial evaporation was investigated by spraying SrZrO(3) powders into water. The influences of spraying current, distance and particle size of the powder on the partial evaporation were also investigated in a quantitative way. With optimized spraying parameters, stoichiometric SrZrO(3) coating was produced by adding an excess amount of Sr in the precursors before plasma spraying to compensate for the volatilized component.
