This course aims to give a fundamental knowledge on the physical chemistry of metals and then to apply the relevant concepts for a basic understanding of corrosion phenomena.
Expected learning outcomes
Students will know basic concepts in the science of metals and in electrochemistry, acquiring a fundamental knowledge of corrosion and of the strategies aimed to prevent it or to protect a metal from being corroded. They will be able to study a corrosion phenomenon, to distinguish among different type of corrosions, to choose the best strategies to prevent corrosion and to protect metals, including the selection of the most suitable metallic materials.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
-Introduction to the Science of Metals: free-electron theory, elementary band theory. -Introduction to Electrochemistry: thermodynamics and kinetics, Pourbaix diagrams, electrocatalysis. -Corrosion: introduction, electrochemical description of corrosion (mixed potential theory, Evans diagrams), passivation and trans passivation. Localized corrosion. Other types of corrosion (galvanic, stress-corrosion, intergranular, dealloying). -Protection against corrosion.
