On the mechanical behavior of brittle coatings and layers

摘要: This paper examines several important issues concerning the mechanical properties of coatings, films, and layers. Major emphasis has been placed on descriptions residual stresses their influence failure coating. The are shown to depend details coating or oxidation process, general curvature substrate, waviness coating-substrate interface, stress relaxation characteristics Residual stress-induced failures, which consist either fractures spalling, described. latter is usually more serious afforded primary attention. It that spalling a consequence buckling, when subject significant compression. conditions needed induce buckling subsequent
