"Brown Nails" by Amanda Kuker, Sara Waters and Kat Mireles, of the New Mexico Tech Materials Advantage Chapter. This new hit song describes the pain and the heartbreak of corrosion. In June 2011, the ASM Foundation selected this song to be a Materials Radio Podcast (click on the purple tab labeled, 'The Science of Materials'), or you can listen to it here, BrownNails.mp3

photovoltages on metals immersed in a liquid. J.R. Birch and T.D. Burleigh,

The photocurrents are result from light exciting electrons in the oxide film, in the presence of a
Schottky barrier. The electrons are excited from the valence band (V.B.) to the conduction band (C.B.)
where they flow down hill under the influence of the electric field. The electric field is a result of the
mismatch of the Fermi levels of the electrolyte and the metal.

Thermal Oxidizing," Corrosion (2000), 56, 12, 1233-1241.

The photocurrents may be used to identify the crystal structure of the titanium oxide since the different oxides
have different bandgaps.

Thermal Oxidizing," Corrosion (2000), 56, 12, 1233-1241.

The active-passive transition of may be modeled as a semiconductor film that becomes degenerate at
high or low potentials. During degeneracy, the conduction or valence bands bend across the Fermi level and the
oxide becomes an electric conductor. from T.D. Burleigh, "Anodic Photocurrents and Corrosion Currents on
Passive and Active-Passive Metals," Corrosion (1989), 45, 6, 464-471

The tarnishing of silver requires an atmosphere containing hydrogen sulfide, oxygen and water vapor.
A electrochemical mechanism is proposed for the tarnishing of silver.

A corrosion chimney forms above the corroding pit on aluminum corroding in saltwater.

Corrosion (1995), 51, 1, 50-55. (Corrosion1995.pdf)
|
Silver may be protected from tarnishing by a self-assembled monolayer (SAM) of hexadecanethiol. The SAM is
prepared by cleaning, etching, rinsing, then immersion in a thiol solution for a certain time period. Too short of time
leads to an incomplete film, and too long of time leads to pinhole corrosion.
