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。
Effect of Y2O3 and La2O3 additives on micros truc hardness and corrosion resistance of the ceramic layer has been studied. The experiment shows that Y2O3 and La2O3 additives reduce porosity of the ceramic layer,increase the corrosion resistance to a certain degree. La2O3 has a better effect than Y2O3 on improving the property of ceramic layer.
