HI! I'm looking for information on how to assess the mechanical integrity of ceramic layers on a metal substrate. So imagine you have a ductile base metal with an oxide outer layer. Stainless steel with chrome oxide outer surface. Now in tension or a 3 point bend test how do you assess how the oxide layer cracks and debonds. Specifically I"m interested in interfacial strength and oxide layer thickness as critical parameters to keeping the oxide stuck to a deforming substrate. I've never thought about this but any experiences, references or ideas are most appreciated.
Thanks.
