In-situ observation of crack propagation in thermally sprayed coatings
Surface and Coatings Technology, 2010•Elsevier
In-situ observation of thermally sprayed coating fractures may complement classical
fractographic analysis to study specific failure mechanisms. In this paper, fracture of free-
standing plasma sprayed ceramic (alumina) and metallic (stainless steel 316L) coatings
during 3-point bending (3PB) was observed in-situ using a scanning electron microscope
(SEM) in order to identify the most important failure mechanisms. Observations were
supplemented by fractographic analysis of fractured specimens.
