Nowadays, many industrial sectors, and among them transport, are intended to improve both mechanical and chemical properties of surfaces to increase their durability, such as thermochemical broadcast treatments; surface treatments by wet - chemical - electrochemical - plasma routes; inorganic, organic, and hybrid coatings, etc. Whether as support for the development and for the optimization of surface treatment in accordance with regulations (ex: REACH), or as a means of control and audit materials and failures, the electron spectroscopies show a real interest for R&D activity. It is thus now that the XPS and Auger spectroscopies, only dedicated to fundamental academic research in past decades, are making a remarkable contribution in the innovation of new processes for improvement of surfaces and facilitating their transfer to industry. As part of (electro)chemical surface treatment of metal alloys, from the initial preparation of the substrate up to its protection by a thin coating, varied and complementary examples will come to account for the extraordinary potential of the electron spectroscopies. Spectral signature, whether from surface or in depth, or from chemical mapping survey (Figure 1), will have as many opportunities to identify phenomena at interfaces or to reveal unexpected behaviors. Different industrial issues will be reviewed, such as adhesion of rubber to steel in reinforcement material in belted radial tires, and eco-friendly anti-corrosion coatings for aircraft aluminum alloys.
