Characterization of Anodized Niobium Surfaces
Anodization is a technique that is utilized for a number of different situations, including protection of surfaces or formation of anodic layers on particle accelerator walls. Once a metal has been anodized, the oxide layer can affect some of the characteristics of the surface of the metal sample, most notably, the color. By anodizing a metal at a certain voltage, we can manipulate the wavelengths of light reflected or absorbed by the surface of the sample. In this presentation we will show how the anodizing process has changed the color of niobium metal surface and describe the relationship between the observed color and the thickness of the niobium-oxide layer.
