Abstract
A turbine engine component has a substrate and a thermal barrier coating deposited onto the substrate. The thermal barrier coating comprises a ceramic material having a sodium containing compound incorporated therein. The sodium containing compound is present in a concentration so that when molten sand reacts with the coating, sodium silicate is formed as the by product.
