Corrosion phenomena do not only occur during operation or maintenance of plants or devices: their prevention is of paramount importance already during the fabrication, testing or storage of components or assemblies in order to minimise the associated risks. Starting from the analysis of specific cases studied by the metallurgy and metrology section of the TS department in the recent years, the significance of corrosion phenomena for the LHC and its experiments is analysed. Through the examples and the failure analyses presented, the seminar will discuss some corrosion mechanisms relevant for the materials of different components of the machine and the detectors. The identification of their causes can allow restrictions to be introduced in due time in the fabrication, joining and testing procedures of components and assemblies, that can be crucial in preventing and minimising present and delayed deleterious corrosion effects, and contribute to the future reliable operation of the machine.
