Rate My Professor Randy John

John's research specializations focus on high-temperature corrosion of engineering alloys used in petrochemical and refining processes. His interests include sulfidation/oxidation mechanisms, alloy selection for harsh environments, corrosion prediction using information systems such as ASSET and SweetCor, carburization, and thermochemical analyses of corrosion products in complex gases. He has expertise in developing corrosion databases, regression analysis for corrosion rates, and engineering assessments of alloy performance. Key publications include a chapter in Uhlig's Corrosion Handbook, Third Edition (2011); the patent "Subsurface heaters with low sulfidation rates" (2013); "Carburization and oxidation of heat resistance alloys at 1800°F (982°C) in CH₄-H₂O gas mixtures" (2007); "Sulfidation/Oxidation Laboratory Tests To Relate To Industrial Conditions" (2007); "Improvements on de Waard-Milliams Corrosion Prediction and Applications to Corrosion Management" (2006); "Predicting Equipment Lifetimes with High Temperature Corrosion Data" (2004); "Assessing corrosion in oil refining and petrochemical processing" (2004); "Sulfidation corrosion in the presence of oxidizing gases" (2004); "Predictions of Corrosion Products for Alloys Corroding in Complex Gases via Thermochemical Analysis" (2003); and "New Understanding of Corrosion of Alloys in High Temperature Sulfidizing Gases" (2002). His work has received 259 citations, contributing to advancements in corrosion mitigation and materials selection for high-temperature applications.
