Burleigh Corrosion Consultants (BCC) provides expert assistance for problems related to corrosion or metallurgical failures. The founder and principal investigator, Dr. Burleigh, has worked in the field of electrochemistry and corrosion since 1982. He completed his Ph.D. in Metallurgy at M.I.T. in 1985 in the Uhlig Corrosion Lab. He continued research in passivity of metals and photoelectrochemistry at the Max-Planck-Institute for Physical Chemistry in Berlin, Germany. Dr. Burleigh worked as a Senior Engineer and Staff Engineer in the corrosion group at Alcoa Technical Center for over five years. At Alcoa he conducted failure analyses, and also designed corrosion tests for aluminum alloys and products. He is a certified "Corrosion Specialist," by NACE International, a registered "Professional Engineer" in Metallurgy in New Mexico, and is trained in "Failure Analysis" by the Materials Engineering Institute of ASM. Dr. Burleigh established BCC in 1993, in order to help small and large businesses solve their corrosion problems and to provide expertise in metallurgical failure analysis. Dr. Burleigh has been a faculty member in the Materials and Metallurgical Engineering Department at New Mexico Tech since 2001.

Selection of Dr. Burleigh's students' work:

"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 (search for "Brown Nails"), or you can listen to it here, BrownNails.mp3

"Demon Chlorides attack Castle Steel" In April 2013, for a class assignment, one of Dr. Burleigh's students wrote this cartoon explanation of the role of nitrogen and molybdenum in preventing pitting corrosion of stainless steel. The student 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 Beginnings of Gold Electroplating" In April 2012, as a class assignment, Jill Garcia wrote an excellent paper on the history of gold plating. We expanded this paper to include the role of The Electrochemical Society in turning the black art of gold plating into a science.

Selection of Dr. Burleigh's work:

"Failure Analysis of Materials - An Introduction" by T.D. Burleigh (2018), ISBN: 978-1-387-45720-5, available at www.Lulu.com. This textbook covers the important steps in conducting a failure analysis, without boring the student to death. A material failure is defined as a part breaking unexpectedly. The part can be metal, plastic, ceramic, or glass, and by breaking we mean that there is a fracture face or damaged surface to examine. Failure analysis is the science of determining how and why the part broke. An accurate failure analysis is key to making a better product. If one does not understand why a part failed, the it is only guesswork as how to fix it. Failure analysis of materials is a multi-disciplinary field because it requires people skills in asking the right questions, engineering skills in calculating the stresses, and metallurgical skills in understanding the alloys and interpreting the micrographs. The final skill is writing a comprehensive report. These topics and more are covered in this book.

"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, NM, 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.

"How to Anodize Steel" may been seen at https://www.youtube.com/watch?v=7g-azzYnMYo
This 2015 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.

"Corrosion of Aluminum Alloys" may be seen at http://youtu.be/YeFTEzeX56k
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.

(Gibeon meteorite)
The polished, etched and heat-tinted face of the Gibeon Meteorite shows a crystal pattern denoting a cooling rate of 1 C per million years (from the Materials and Metallurgical Engineering Department Brochure).

A schematic of the photoelectrochemical apparatus used for measuring photocurrents and photovoltages on metals immersed in a liquid. J.R. Birch and T.D. Burleigh, "Oxides Formed on Titanium by Polishing, Etching, Anodizing, or Thermal Oxidizing," Corrosion (2000), 56, 12, 1233-1241. (BirchBurleigh2000.pdf)

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. Burleigh, "Oxides Formed on Titanium by Polishing, Etching, Anodizing, or Thermal Oxidizing," Corrosion (2000), 56, 12, 1233-1241. (BirchBurleigh2000.pdf)

The photocurrents may be used to identify the crystal structure of the titanium oxide since the different oxides have different bandgaps. J.R. Birch and T.D. Burleigh, "Oxides Formed on Titanium by Polishing, Etching, Anodizing, or Thermal Oxidizing," Corrosion (2000), 56, 12, 1233-1241. (BirchBurleigh2000.pdf)

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 (Corrosion1989.pdf)

The tarnishing of silver requires an atmosphere containing hydrogen sulfide, oxygen and water vapor. A electrochemical mechanism is proposed for the tarnishing of silver. T.D. Burleigh, Y. Gu, G. Donahey, M. Vida, D.H. Waldeck, “Tarnish Protection of Silver using a Hexadecanethiol Self-Assembled Monolayer and Descriptions of Accelerated Tarnish Tests,” Corrosion (2001), 57, 12, 1066-1074. (BurleighWaldeck2001.pdf)

A corrosion chimney forms above the corroding pit on aluminum corroding in saltwater. T.D. Burleigh, E. Ludwiczak, and R.A. Petri, "Intergranular Corrosion of an Al-Mg-Si-Cu Alloy," 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. Figure 10b from T.D. Burleigh, Y. Gu, G. Donahey, M. Vida, D.H. Waldeck, “Tarnish Protection of Silver using a Hexadecanethiol Self-Assembled Monolayer and Descriptions of Accelerated Tarnish Tests,” Corrosion (2001), 57, 12, 1066-1074. (BurleighWaldeck2001.pdf)

Zinc corrodes faster under UV illumination. E.A. Thompson and T.D. Burleigh, "Accelerated Corrosion of Zinc Alloys Exposed to Ultraviolet Light," Corrosion Engineering, Science and Technology (2007), 42, 3, p. 237-241. (Zinc&UV_2007.pdf).

A corrosion resistant Mg-Li alloy is made by alloying with scandium. T.D. Burleigh, R.K. Wyss, "Dual Phase Magnesium Based Alloy having Improved Properties," U.S. Patent No. 5,059,390 (October 22, 1991). (MgLiSc.pdf)

Improvement in the erosion corrosion resistance of Cu-10%Ni was achieved by adding indium. T.D. Burleigh and D.H. Waldeck, "Effect of Alloying on the Resistance of Cu-10% Ni Alloys to Seawater Impingement," Corrosion (1999), 55, 8, 800-804. (Corrosion1999.pdf)
