The goals of this course are recognized at the design of a product it's susceptibility to corrosion in order to optimize the choice of material and its conditions of use, and select a suitable and sustainable corrosion protection (type, mode of application, quality control)
Learning objectives
This course is an introduction to corrosion mechanisms. We thus define successively all modes and types of corrosion of metallic materials as well as the main modes of surface treatment. The objective is to obtain the necessary concepts to provide recognition from the design of a product's susceptibility to corrosion in order to optimize the choice of material and its conditions of use, and to select an anti-corrosion protection adequate and sustainable (type, mode of application, quality control)
