Latest Patents
David S. Mitch's most recent patents reflect his expertise in galvannealed electroplated steel. His first patent, titled "Induction Galvannealed Electroplated Steel Strip," describes a method of heating a steel strip to an alloying temperature exceeding 427°C using an induction coil. This technique produces an eddy current that penetrates half the thickness of the strip. The careful control of diffusion temperature and time is pivotal in minimizing the formation of brittle gamma alloy phases in the zinc/iron alloy coating.
His second patent, "Process for Controlling Zinc Vapor in a Finishing Process for a Hot Dip," outlines a technique to manage zinc vapor during the finishing of hot-dip zinc-based coatings on ferrous metal strips. The process involves injecting high dew point gas into an enclosed chamber where the coated strip emerges from the bath, ensuring that about 1-3% water vapor is maintained for effective coating on either side of the strip.
