Abstract
This study investigates the mechanical response of plasma-sprayed ceramic coatings to different levels of mechanical and thermal loading. Test samples were subjected to four-point bending and thermal cycling loads. Nonlinear behavior and significant hysteresis were observed, indicative of inelastic phenomena. Previous tests were complemented by structural examinations and bonded-interface testing. Relevant structural features and possible mechanisms underlying this behavior are discussed.
