Abstract Tribocorrosion is of complex nature as it involves multiscale interactions between mechanical, (electro-)chemical, physical, and material factors. The influence of mechanical stresses/strains on the surface reactivity of metallic alloys is described here. The electrochemical behavior and the corrosion resistance of engineering alloys are discussed in the presence of compressive and tensile stresses through different examples. The role of physical (formation of steps, roughness, microcracks), metallurgical (dislocations, crystallographic texture, and grain size), and chemical (passive film composition) changes induced by plastic deformation on electrochemical behavior and corrosion resistance of alloys is also discussed. Throughout the chapter, examples in corrosion and tribocorrosion studies are presented.
