| 研究采用等离子体喷涂制备纳米结构YPSZ涂层。通过X射线衍射分析、扫描电子显微镜对纳米结构YPSZ涂层的耐腐蚀性与涂层的微观组织结构的关系进行研究。结果表明：由于涂层孔隙尺寸的降低，孔隙率的增大使纳米结构YPSZ涂层的耐盐腐蚀性能降低，耐高温腐蚀性能提高。纳米结构涂层经过盐腐蚀或高温腐蚀后纳米晶粒明显长大，并出现微小的晶格变化及相转变现象。 |

| Abstract: |
| Nanostructure YPSZ coating was fabricated by plasma spraying technology. The coating composition was analyzed by IR-FT and XRD. The coating structure and porosity were observed by SEM. The corrosion resistance of ceramic coating was examined by salt immersion and high temperature oxygen experiments. The results show that the corrosion resistance of the coating is decreased because of the increase of porosity, and the property of high temperature oxygen is improved. After salt and high temperature corrosion, the growth of Nanostructure crystalline size and phase transformation are observed. |
