Hydrogen entry into AISI 4135 high strength steel in tribocorrosion environment was studied in the present study. The samples were corroded in tribocorrosion environment using a pin-on-disk type wear gear equipped with a solution cell and in static corrosion environment, and the hydrogen content entered into the steel was measured using hydrogen thermal desorption analysis. The hydrogen content in tribocorroded sample was larger than that in corroded sample without wear. From the cathodic polarization curves and surface morphology, it is revealed that the main factor which increases the amount of entered hydrogen is solution flow. The solution flow enhances the supply of oxygen, and the difference of flow rate forms anodic and cathodic areas on the samples. Solution flow also enhances anodic dissolution and increases hydrogen generation reaction. As a result, hydrogen entry into the high strength steel is enhanced in tribocorrosion environment.

“…Our research group has previously reported that mechanical stress breaks down the passive film and induces localized corrosion of metallic materials. [14][15][16] For example, Ti alloy and stainless steel, which are used as biomedical implants, form a passive film and show high corrosion resistance in the environment of the human body; however, the passive film is broken when it is subjected to fatigue stresses due to the movements of the body such as walking. 16 The implants that are exposed to mechanical stress are expected to have a shorter lifetime when compared to those without mechanical stress.…”

The synergistic effect of plastic deformation and Cl- on corrosion initiation of steel rebars was examined by applying rapid tensile strain and cyclic stress to the steel in a simulated concrete pore solution with various concentrations of Cl-. In a rapid straining electrode test, the passive film of the steel was broken under plastic deformation and the anodic current increased sharply with the onset of slip step formation, whereas it was hardly broken under elastic deformation. Localized corrosion was initiated on the slip steps when the Cl- to OH- concentration ratio ([Cl-]/[OH-]) of the test solution was 0.4 or more. Localized corrosion also occurred under fatigue stress at [Cl-]/[OH-] ≥ 0.4. Experimental results demonstrated that the combination of slip step formation due to local stress concentration and the inhibition of repassivation by Cl- initiated corrosion under a significantly small [Cl-]/[OH-] ratio.

“…Thus, we have performed a series of studies on stainless steels as biomaterials, [30][31][32][33] investigating their corrosion behaviors, and surface modi cations for improvement of osseoconductivity. Such surface modi cations have the potential to promote the application of stainless steels as implant materials.…”

In this study, we evaluated the osseoconductivity of Type 316L stainless steel with self-organized nanopores of three different average diameters (26, 90, and 177 nm), formed by anodic polarization. The proliferation, alkaline phosphatase activity, and morphology of MC3T3-E1 mouse osteoblast-like cells, cultured on the self-organized nanopores were evaluated. The cell densities on samples with the nanopores were higher than those on mechanically nished surfaces that were mirror-polished or ground with #2000 SiC paper. In particular, the highest cell density and alkaline phosphatase activity were obtained on the nanoporous sample with the smallest diameter of 26 nm. Cells on the samples with 26 nm nanopores extended further and spread more lopodia compared with cells on samples with the other surface morphologies. Therefore, we concluded that self-organized nanopores with an optimal diameter (e.g., 26 nm) on Type 316L stainless steel could enhance long-term cell activity.
