Abstract: It is consensus that local spallation failures in thermal barrier coatings (TBCs) are determined synergistically by many factors. The present experimental test results confirm a completely new spallation failure mechanism for the electron beam-physical vapour deposited (EB-PVD) TBCs on engine turbine blades, which is hypothesized in the latest work [1, 2] for the study of thin film spallation. That is, the spallation is driven by pockets of energy concentration (PEC). This paper reports the experimental study.
