Double exposure laser holographic interferometry is implemented to investigate the surface deformation of an stainless steel (SS) 304 substrate during the deposition of titanium dioxide (TiO2) thin films on it. The TiO2 thin film is synthesized by the potentiostatic mode in the electrodeposition process. The in-situ analysis of the stress on the substrate and the thickness of the deposition is evaluated by non-destructive holographic interferometry. The holography interference fringes are computed and show that the TiO2 film thickness increases with an escalation in deposition time, but the stress on the substrate decreases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
