In this study, dense yttria coatings are produced by conventional flame spraying using a yttrium ethylene diamine tetra acetic acid (Y-EDTA) complex as the feedstock powder. By adjusting spray parameters, the organic components in the EDTA are completely decomposed and only crystalline Y2O3 phases are found in the deposits. Compared to atmospheric plasma sprayed Y2O3, Y-EDTA coatings produced by reactive flame spraying have better surface morphologies with fewer microcracks and are obtained at lower cost.
