摘要：

For the first time, the solution precursor high-velocity oxy-fuel spray process was used to deposit Al(2)O(3)-ZrO(2) ceramic coatings. X-ray diffraction analysis and transmission electron microscopy characterization show that the as-sprayed coating is composed of mixed nanocrystalline ZrO(2) and gamma-Al(2)O(3) as well as amorphous phases. The as-sprayed coating consists of ultrafine splats with diameters ranging from 2 to 5 mu m. Few spherical particles, hollow-shell structures are also observed on the coating surface. Polished cross-section shows that the coating is quite dense with a thickness of 40 mu m. (C) 2009 Elsevier Ltd. All rights reserved.
