富硅镱硅化物是通过电弧熔化技术制造的，用作环境屏障涂层系统中的粘合涂层材料。通过在干燥空气和惰性气氛中进行氧化测试来评估其潜力。实验结果表明，测试后观察到的硅化镱重量和形貌的变化取决于氧分压。在空气中氧化后发生广泛氧化并增重。为了将该材料应用于热结构，需要提高抗氧化性。
Si-rich ytterbium silicide was fabricated by through an arc-melting technique for applying use as a bond coat material in an environmental barrier coating system. Evaluation of its potential was accomplished through oxidation tests in dry air and an inert atmosphere. The experimental results showed that the changes in weight and morphologies of ytterbium silicide observed after the tests depended on the oxygen partial pressure. Extensive oxidation and weight gain occurred after oxidation in air. In order to apply this material for hot structures, improvement of the oxidation resistance is needed.
