CORROSION 2021 opened on Monday with the Welcome and Plenary Lecture. AMPP CEO Bob Chalker, AMPP Chair Tim Bieri, and AMPP Global Center Chair Joyce Wright welcomed attendees to the association’s first virtual annual conference before turning it over to Dr. William Hartt for the Plenary Lecture. The Plenary was the first of three special lectures that recognized individuals for their contributions to the field.
In the Plenary Lecture, “Corrosion, Fracture, and Failure Issues for Post-Tensioned Concrete Bridge Structures,” Hartt provided background and history on the types of bridges, post-tensioning, and post-tensioning failures. He gave an overview of his tendon failure projection model, including the variables considered and model validation. Hartt concluded by saying that post-tensioned bridge technology will continue to evolve, however, effective maintenance and monitoring of the existing post-tensioned bridges is needed.
On Tuesday, Dr. Robert Kelly presented the W.R. Whitney Award Lecture. In his lecture, “The Importance of Local Chemistry and Potential in Localized Corrosion and Stress-Corrosion Cracking,” Kelly highlighted some of the work he and his students performed over the years. He walked through some of the challenges with measurement and modeling of localized corrosion and stress corrosion cracking, as well as challenges linking the measurements and models together. Kelly provided some insight on how they overcame these challenges.
Wrapping up the award lectures, Dr. Jose Maria Bastidas presented the F.N. Speller Award Lecture, “Corrosion Mechanisms of Steel and Copper in Engineering Applications,” on Wednesday. He discussed four topics: pitting corrosion of AISI 304 stainless steel, corrosion of steel reinforcements for civil and engineering applications, corrosion and protection of tinplate, and copper corrosion in air-conditioning systems. He concluded by providing trends and challenges pertaining to each of these areas.
These lectures will be available to watch on demand on the conference site until October 31, 2021. Attendees can connect with the lecturers to discuss their presentations and ask any questions.
