It is the passive film (thin oxide), which significantly improves the corrosion resistance of passive metals and alloys such as Ni, Al, and stainless steels being used in many industrial applications. The science behind the development of corrosion resistance alloy (CRAs) depends a lot on the careful selection of alloying elements, which can improve the qualities of this thin protective oxide. These additions can alter the film structure and composition to either improve or degrade the overall performance of the newly developed alloys. The metal/metal oxide/solution interface is a very complex interface, as many electrochemical reactions are occurring at this interface. Therefore, it would be great to use some in-situ characterization techniques to examine the metal/metal oxide/solution interface for ongoing changes that are taking place at this interface. Therefore, both the photoelectrochemical spectroscopy (PES) and Mott-Schottky analysis techniques can be utilized for in-situ investigation of these oxide films. In this chapter, the applications of PES and MS analysis will be discussed along with brief introduction of the both techniques.
