摘要
Abstract
Yttria partially stabilized zirconia ( YSZ) and Lanthanum cerium oxide (LCO) thermal barrier coatings with conventional lamellar and segmented structures were prepared by plasma spray. The result shows that bond strength of segmented YSZ coatings is higher 1.8 times than conventional lamellar coatings. The microstructures of LCO coating are more sensitive to spray process. The intersplat contact between lamellae can be enhanced by advisable reduction spray power, and the presence of branch crack is released. So the formation segmented crack is promoted. Bond strength and thermal shock resistance of LCO/ YSZ coat with segmented structures are not improved compared with conventional lamellar structure coat.关键词
