The use of Ceramic Matrix Composites (CMCs) in the hottest part of an aero engine promises great improvements in fuel efficiency by decreasing component weight and allowing higher gas inlet temperatures. However, an environmental barrier coating (EBC) is required to protect the CMC from the corr...detailed
The preparation, sintering and low-temperature physical properties of four kinds of ytterbium sulfides (η-Yb2S3, ε-Yb2S3, Yb3S4 and YbS) were systematically investigated. The suitable sintering processes were ensured for each ytterbium sulfide. SEM results suggested the sintered ytterbium sulf...detailed
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 sho...detailed
