“…The presence of chloride ions on the passive film results in a concentration gradient and accelerates its diffusion into the film, which stabilize the local acidification generated from metal cations hydrolysis thus leading to active dissolution of the passive film [44]. This phenomenon agrees well with the chloride penetration mechanism [45] that corresponding to the structure of the passive film, particularly the stability of the passive film. Therefore, the decreased localized corrosion resistance of the passive film that formed on the high residual tensile stress AMCs is expected to be associated with a higher defect concentration (e.g.…”

The electrochemical corrosion and passive behavior of activated combustion high-velocity air fuel FeCrMoMnWBCSi amorphous metallic coatings (AMCs) under different geometries that produced a variable tensile residual stresses were investigated in chloride-containing solutions by using electrochemical measurements and X-ray photoelectron spectroscopy. The tensile residual stresses of AMCs were determined by the mechanical method of sharp indentation testing. A systematic detrimental effect of tensile residual stress on passive current density and localized corrosion was found. The detrimental effect of residual stress was aggravated at higher temperatures and acidity. The implication of high donor density on the passive film stability, derived from Mott-Schottky analysis, is also discussed.

“…Interesting approaches have appeared in the recent literature concerning the fundamental interpretation and the modeling of the repassivation kinetics during tribocorrosion [1][2][3] and the potential evolution with time for, e.g., freshly guillotined Al [4,5], but none-as far as the authors are aware-have treated or attempted theoretically to reproduce the complex behavior and the time evolution of the quasi steady-state depassivation-repassivation response of a tribocorrosion sliding experiment, where any perturbation in the potential occurs over the entire electrode surface and the response is a convolution of that from the passive metal surrounding the scratch and that from the relatively very thin scratch itself.…”

Valuable insights into the wear-corrosion behavior of metals, as well as into the tribocorrosion field through the development of simulation models of tribocorrosion experiments, can contribute in rationalizing wearaccelerated experiments and their open circuit potential (OCP) behavior under rubbing. These results demonstrate that mathematical models of controlled tribo-electrochemical contacts can complement the physical experiment and add valuable understanding to the tribological behavior of metals, alloys, and generally to materials in an electrochemically active environment. The excellent agreement of experimental wear data and the experimental OCP curves with the OCP simulations with time establishes the concepts underlying the galvanic coupling model as a valid methodological approach toward a quantitative description and mechanistic understanding of the tribo-electrochemical experiment. Besides analyzing stellite tribocorrosion, application of the model to Al alloy data has helped us quantify the relative contributions of chemical and mechanical wear and reveal the underlying synergy. Ti metal tribocorrosion under variable load has revealed that the contact pressure P av , can reach much lower values within the experimental time domain and finally be the cause of interruption of the initial wear mechanism.

Metals and alloys such as aluminum (Al), stainless steels, and nickel-based alloys exhibit corrosion resistance in a wide range of environments due to the presence of protective, passive oxides. However, in environments that contain aggressive anions such as chloride, Cl − , the passive film becomes unstable and degrades locally causing film breakdown and pitting corrosion. A number of theories describing the initiation of pitting corrosion have been postulated and discussed but to date there is no consensus on the mechanism of breakdown. Since all current mechanisms require Cl − interactions for oxide film breakdown in Cl − containing environments, the question is what is the nature of the interaction of aggressive anions such as Cl − with the passive film, adsorption and/or absorption, leading to pitting? This communication focuses on the interaction of Cl − with the passive oxide film on pure aluminum by reviewing and summarizing the available experimental data concerning Cl − interactions. It should also be noted that the observations for Cl − interactions with Al reviewed and summarized herein might not be applicable to all metals and alloys. Technologically important metals and alloys such as aluminum (Al), stainless steels, and nickel-based alloys exhibit corrosion resistance in a wide range of environments due to the presence of protective, passive oxides.1-90 The passive oxides behave as kinetic barriers, which inhibit further oxidation of the underlying thermodynamically reactive metals. However, in environments that contain aggressive anions such as chloride, Cl − , the passive film becomes unstable and degrades locally causing film breakdown and localized corrosion, which in turn decreases the service life of the materials. The consequence of discrete oxide failure is localized corrosion, which occurs in the forms of crevice corrosion in occluded sites and metastable or stable pitting corrosion on open surfaces. It is generally agreed that localized corrosion occurs in two distinct steps: initiation and propagation.A number of theories describing the initiation of pitting corrosion have been postulated and discussed.
