Abstract
Developing new systems with excellent properties is of great significance to the progress of TBC. We herein study the CMAS corrosion behavior of four A6B2O17 ceramics to evaluate the feasibility for TBC application. Zr6Nb2O17 has the worst corrosion resistance and Hf6Ta2O17 shows the best. The effects of elements A and B are reflected in the differences of corrosion products and reverse dissolution process, respectively. The dense corrosion layer containing CaTa2O6 and HfSiO4 is an important factor for Hf6Ta2O17 to prevent further corrosion. The present results highlight the merit of Hf6Ta2O17 as a promising candidate for CMAS-resisted TBC.
