Metal Science and Corrosion

A.Y. 2019/2020
Overall hours
Learning objectives
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.
