“…In a recent paper, Dalbert et al, used an exponential current decay to approximate the response to film removal in tribocorrosion experiments. 6 This was shown to give a good fit to experiment curves. A similar approach was also used by Mary et al, 7 who used an evaluation path suggested by Okorie and Nowak, 8 involving two exponential functions with one time constant representing film nucleation on a bare metal surface, and the other film growth.…”

Tribocorrosion of passivating metals is a dynamic phenomenon causing degradation of materials by a combination of mechanical wear and electrochemical dissolution. The mechanical action typically produces a local removal of particles, metal as well as oxides, resulting in an exposure of the metal surface and is followed by a repassivation process, of which the time-dependent current response is a direct measure. Kinetics for interface-limited film growth were used to find an analytical expression for the current transients, including the conductivity of the electrolyte as well as the contribution from the confined geometry within the mechanical contact. The solution gave a good experimental fit to a series of experiments with a range of electrolyte conductivities, and also to correlate well with values obtained using electrochemical impedance spectroscopy. Parameters from the rubbing experiment were used to calculate curves that compared well with passivation transients recorded on a bare metal surface for the same electrolyte series. The evaluation procedure made it possible to assess the relative resistance contributions from the growing passive film, the confined mechanical contact geometry, and the electrolyte.

“…Passive film dynamics and transient current in corrosion for passivating metals have been extensively studied and there is a vast literature, e.g., compilations can be found in general textbooks such as those by Kaesche and Marcus [100,101]. There have also been studies on the measurement [102][103][104] and modelling [79,99,105] of corrosion and corrosion current decay during tribocorrosion test. Dalbert et al [104] used an exponential current decay function to approximate the response to film removal in tribocorrosion experiments and showed a good fit to experimental curves.…”

Wear by hard particles can involve abrasion or erosion and is one of the most severe forms of wear. When a corrosive environment is present, the material loss rate can be significantly increased due to interactions (synergy) between the mechanical and chemical/electrochemical actions. In developing strategies for mitigating such adverse synergistic effect, it is important to understand the complex effect of various parameters on material loss under given tribocorrosion conditions. In this paper, a model is presented for wear-corrosion synergy in abrasive wear by hard particles applicable to many conditions in both the marine renewable (abrasion by high concentrations of large sand particles on tidal turbines) and extractive metallurgy (abrasive wear in mineral extraction). The mechanical wear loss is modeled based on the grooving mechanism (micro-cutting/micro-ploughing). Wear-enhanced corrosion is calculated from the fresh surface areas generated by grooving and the corresponding transient corrosion current. The concept of “corrosion-degraded layer” on the worn surface is introduced to account for the corrosion-enhanced wear; within this corrosion-degraded layer, the material loss rate is higher under the same mechanical wear conditions than in the material that is unaffected by corrosion. Based on the model, the effect of wear conditions on synergy in hard particle wear-corrosion has been discussed. The relative thickness of the corrosion-degraded layer to the depth of hard particle penetration (grooving) in the mechanical wear is found to be an important parameter in determining the relative severity of synergy in different tribo-corrosion systems. Good qualitative agreement has been observed between the predictions and published experimental results obtained from a range of abrasion-corrosion and erosion-corrosion lab testing.

“…In-situ optical imaging and thermography techniques are also useful tools to characterize wear degree of mechanical parts during laboratory testing. These monitoring methods have been used in silicone nitride ball sliding on steel disc under dry condition [388], in-situ determination of wear surface during tribocorrosion tests of ferrite stainless steel in sulphate solutions [389], and analysis of the role of the glaze layer generated in a cylinder-on-flat fretting wear test of 310S stainless steel [390]. Woski et al [391,392] discussed the automated classification of worn surfaces based on image analysis of wear scars.…”
