This document specifies a method for measuring the reproducible linear thermal expansion coefficient of ceramic top coats (TCs) for thermal barrier coatings (TBCs) up to 1 300 °C.
Abstract
Overview
ISO 22680:2020 specifies a standardized method to measure the of ceramic top coats (TCs) used in thermal barrier coatings (TBCs) - up to . It addresses reproducible measurement of TC dilatation behavior (not the metallic bond coat or substrate) and fills a gap left by standards that target monolithic ceramics. The procedure covers specimen preparation, apparatus requirements, measurement cycles and reporting essentials.
