In-situ ellipsometric determination of thickness and optical constants of passive and transpassive films on alloy 600 in neutral solution

In-Situ ellipsometric measurements coupled with electrochemical techniques have been performed on Alloy 600 in a neutral solution at various temperatures ranging from 293 to 368K. Three characteristic potential regions, that is, the passive, the primary transpassive and the secondary transpassive re...

Description
Summary:In-Situ ellipsometric measurements coupled with electrochemical techniques have been performed on Alloy 600 in a neutral solution at various temperatures ranging from 293 to 368K. Three characteristic potential regions, that is, the passive, the primary transpassive and the secondary transpassive regions were observed on film thickness versus potential curves. The effect of temperature on the thickness end the optical consant for films was remarkable in the primary and the secondary transpassive regions.
