W. Stephen Tait
Dr. Stephen Tait is the Chief Science Officer and Principal Consultant for Pair O Docs® Professionals L.L.C. He has 40 years of experience with all aspects of anti-corrosion technology, and investigating failure of metal structures. He has developed numerous corrosion prevention and control programs for food and aerosol containers, vacuum-deposited coatings on glass, consumer electrical appliances, chemical processing equipment and chemical reactors, gas refinery cooling towers, and both commercial and consumer transportation vehicle coatings. Dr. Tait is an industry leader in electrochemical corrosion testing, and the application of reliability engineering to packaging for consumer products. He holds eight U.S. and foreign patents on corrosion measurement equipment, corrosion inhibitors, a device for monitoring crevice corrosion, and is the inventor of the Tait Cell, GEN2, GEN3 and GEN4 Multi-cells, and the Flexi-cell for electrochemical testing. His unique combination of education in metallurgy, chemical engineering and chemistry, plus his extensive experience and knowledge on all aspects of metal package construction, filling, corrosion, and modes of failure make him an ideal expert witness for litigation involving metal package failures. Dr. Tait developed and managed a world-class corrosion research and testing laboratory while at S. C. Johnson. This laboratory included two satellite laboratories in Europe and China. Test results from these labs allowed low-risk rapid introduction of new products and prevention of both packaging and equipment failure by corrosion. Earlier, with Petrolite Corporation (a specialty chemical manufacturer for the petrochemical industry) he developed corrosion prevention and control programs for the petrochemical industries. Dr. Tait, an accomplished technical author, wrote the textbook on electrochemical corrosion testing. Over 1300 copies of his book have been sold worldwide to industries, universities and government laboratories since its publication in 1994. He writes Corrosion Corner, a monthly column for Spray Technology & Marketing magazine, and has authored and presented over 80 technical papers and chapters in books. He also is a peer reviewer for many of the technical journals in his field. His teaching experience spans over 40 years and includes traditional university classroom and continuing professional education courses in chemistry, chemical engineering, corrosion and materials engineering, corrosion science and prevention. He was also an adjunct full professor at the University of Wisconsin-Milwaukee from 2000 to 2003. Dr. Tait is certified by NACE International as a Corrosion Specialist. He is one of eighteen specialists worldwide who are certified by that organization in chemical treatment of corrosion (formulation of corrosion inhibitors). He is a member of NACE International; the Electrochemical Society; and ASM International.
