Adhesion of a substrate onto a cmc component

A method of adhering a substrate onto a surface of a ceramic component, the method comprising:

• applying a first bond coating onto an attachment surface defined on a plate of the substrate;
• applying a first alumina coating onto the first bond coating on the attachment surface of the substrate;
• applying a second bond coating onto an outer surface of the ceramic component;
• applying a second alumina coating onto the second bond coating on the outer surface of the ceramic component;
• applying a cement onto at least one of the first alumina coating and the second alumina coating;
• and
• adhering the attachment surface of the substrate onto the outer surface of the ceramic component,
• wherein the substrate further comprises a stem and a probe, the plate extending outwardly from the stem and the probe between at least one retainer arm and the ceramic component, the at least one retainer arm extending from the stem and spaced apart from the plate.
