ResumoThe effect of cycle frequency on the spallation failure of thermal barrier coatings has been investigated. The exposure conditions affect the lifetimes of the coatings and can even change the relative performance of different bond coats. The very strong effect of exposure temperature is consistent with thermally grown oxide growth being a first order variable in scale failure.
