| 中文摘要 | thermal barrier coatings (tbcs) of la2zr2o7 (lz) with the addition of 3 wt.% y2o3 (lz3y) were deposited by electron beam-physical vapor deposition (eb-pvd). the phase stabilities, thermophysical and mechanical properties, and chemical compositions of these ceramics and coatings were studied in detail. the phase stability and thermal expansion behavior of lz3y bulk material are identical to those of lz bulk material, but the mechanical properties of the former are superior to those of the latter. elemental analysis and x-ray diffraction indicate that compositional deviation of lz coating can be optimized after doping by 3 wt.% y2o3, y2o3 acts as a dopant as well as a process regulator. the optimal composition of lz3y coating could be effectively achieved by the addition of excess y2o3 into the ingot and by properly controlling the current of electron beam (i.e. similar to 650 ma). |
