Hot Corrosion Behavior of Yttria-Stabilized Zirconia in the Presence of CMAS and CMAS + NaVO3 Mixture

Coatings
The aim of this paper is to study the corrosion mechanism of CaO-MgO-Al2O3-SiO2 (CMAS) powder and CMAS + NaVO3 (hereafter referred to as CN) mixed powder on a yttria-stabilized zirconia (YSZ) block at different temperatures. In this paper, the CMAS and CN corrosion behavior of YSZ at 1200 °C and 1250 °C was studied.
