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.
Course syllabus and organization

Single session

Responsible
All lessons will be held in SYNCHRONOUSLY and the videos will be regularly uploaded on the ARIEL (https://aminguzzimsc.ariel.ctu.unimi.it/v5/home/Default.aspx ; one video for every 2 hours of equivalent frontal lesson) and on the MS Teams websites.
The teacher will be available on demand (after appointment) for supplementary explanations and for Questions & Answers sessions on the ARIEL forum and on MS Teams.
Any other notice or warning relevant to the course will be posted on the ARIEL's notice boards. Please, check it regularly.
Course syllabus
-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 cracking, etc.).
-Protection against corrosion.
-Correct choice of metallic materials, particularly in the chemical industry
Prerequisites for admission
Competences and knowledge on physical chemistry (thermodynamics and kinetics, basic quantum mechanics), on mathematical analysis (function analysis and infinitesimal calculus) and on basic physics (electromagnetism)
