| 摘 要： | 研究了钇、镧等添加物对金属陶瓷内衬显微硬度和耐蚀性的影响。结果表明:加入Y2O3、L a2O3和S iO2可使陶瓷层的孔隙度降低,一定程度上使耐蚀性增加。L a2O3对提高陶瓷层性能的效果比Y2O3要好。

| Abstract: | Effect of Y_2O_3 and La_2O_3 additives on microstruc hardness and corrosion resistance of the ceramic layer has been studied.The experiment shows that Y_2O_3 and La_2O_3 additives reduce porosity of the ceramic layer,increase the corrosion resistance to a certain degree.La_2O_3 has a better effect than Y_2O_3 on improving the property of ceramic layer. |
