| 摘 要： | 利用化学共沉淀法制取锆酸镧(La2Zr2O7,简称LZ)和La2O3-CeO2-ZrO2(简称LCZ)热障涂层喷涂粉,采用电感耦合等离子体光谱仪(ICP-AES)对粉的化学成分进行分析,用X射线衍射仪分析LZ,LCZ的物相组成,用差式扫描量热法研究粉的高温相稳定性.结果表明:LZ,LCZ粉均为烧绿石结构;高温下LZ,LCZ无明显相变. |

| Abstract: | Lanthanum zirconate (La2Zr2O7, LZ) and La2O3-CeO2-ZrO2(LCZ) powders for thermal barrier coatings were prepared by coprecipitation. The chemical composition of the powders were analyzed by means of Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). Crystallogrphic phases were determined by X-ray diffraction technique. Differential Scanning Calorimetry (DSC) was used to analyze the phase stability at high temperatures. The results showed that both LZ and LCZ powders kept the pyrochlore structure and there were no phase transformations for LZ and LCZ at high temperatures. |
| Keywords: | lanthanum zirconate thermal barrier coatings coprecipitation |
