摘要

The hot corrosion behavior of Mg₂SiO₄ ceramic was investigated in molten V₂O₅ at 700–1050 °C. Mg₂V₂O₇ and SiO₂ were the main corrosion products which were almost temperature independent. The corrosion layer consisted of two zones. The planar reaction zone (PRZ) was very thin due to the chemical inertness of Mg₂SiO₄ with V₂O₅, while the infiltrated reaction zone (MIRZ) was thick due to the high porosity of the ceramic. The depth of MIRZ increased rapidly with the increase of temperature, indicating that thermo-mechanical damage caused by V₂O₅ infiltration might be the main degradation mechanism of the Mg₂SiO₄ based thermal barrier coatings.
