Dr. T. David Burleigh is a Professor of Materials and Metallurgical Engineering at New Mexico Tech. He is specializes in the corrosion of metals and in metallurgical failure analysis. Dr. Burleigh has taught a variety of courses at New Mexico Tech, and the most recent ones are listed above.

In his corrosion research laboratory, students work on several corrosion research projects, including the corrosion of copper alloys and the anodization of steel. Dr. Burleigh is a certified "Corrosion Specialist" by NACE International, and a registered "Professional Engineer in Metallurgy," in New Mexico. He completed his Ph.D. in Metallurgy at M.I.T. in 1985 conducting research in the Uhlig Corrosion Lab. He continued research in photoelectrochemistry and passivity at the Fritz-Haber-Institut (Max-Planck-Institute for Physical Chemistry) in West Berlin, West Germany. Dr. Burleigh worked in the corrosion group at Alcoa Technical Center for over five years designing alloys, corrosion tests, and testing products.

Since 1993 he has been the principal investigator for Burleigh Corrosion Consultants, where he solves corrosion problems for small and large businesses. Prior to coming to New Mexico Tech, he was a Research Associate Professor at the Materials Science and Engineering Dept. at the University of Pittsburgh where he taught and also conducted research in aqueous corrosion.

A chemical equation showing how steel corrodes in water."Corrosion of Steel in a Waterdrop" may been seen at http://www.youtube.com/watch?v=d0LUB90uDaEm 

This video is a series of time-lapse micrographs taken by Dr. Burleigh in 2011. These timed micrographs show a water drop containing pH indicator solution, sitting on the surface of bare steel. The water drop is Socorro municipal water, containing many dissolved minerals including 14 ppm NaCl. As time progresses, the color of the pH indicator solution changes, indicating that acidic and caustic regions are developing in the water drop. Dr. Burleigh narrates the micrographs and explains the corrosion phenomena witnessed in the video.

This video describes the methods developed by Prof. Burleigh and his students for anodizing steel in hot caustic electrolytes. This process is the subject of two publications. The anodized layer is a nano-porous magnetite film that is adherent to the surface. The reflection of light from the top and bottom surfaces of the oxide film create a dichromic color that changes with viewing angle.

This educational video (produced by Dr. Burleigh in 2014) is a brief introduction into the corrosion of aluminum alloys. The video shows the common forms and the theoretical mechanisms of aluminum corrosion. This video was funded by a grant from Modern Light Metals.

Cartoon drawing of stick figures representing nitrogen and molybdenum."Demon Chlorides attack Castle Steel" 

One of Dr. Burleigh's students wrote this cartoon explanation of the role of nitrogen and molybdenum in preventing pitting corrosion of stainless steel. He currently wishes to remain anonymous. This cartoon is based on the cartoon presented by Prof. Koji Hashimoto in 1983 at The Fifth International Symposium on Passivity in Bombannes, France. Prof. Hashimoto first introduced the demon chlorides and the good mother Molly. This cartoon has added the characters, nanny nitrogen, cousin carbon, and harlot hydrogen.

The photocurrents are result from light exciting electrons in the oxide film, in the presence of a Schottky barrier.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. J.R. Birch and T.D.

Image of a graph showing how silver may be protected from tarnishing by a self-assembled monolayer of hexadecanethiolSilver 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. Figure 10b from T.D. Burleigh, Y. Gu, G. Donahey, M. Vida, D.H.
