The mechanics of interface fracture in layered composite materials: (6) spallation of thermal barrier coatings of turbine blades
conference contribution
posted on 2017-06-23, 14:36 authored by Bo Yuan, Christopher HarveyChristopher Harvey, Rachel ThomsonRachel Thomson, Gary Critchlow, Simon WangIt 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.
