The corrosion of steel reinforcement negatively influences the mechanical performance reinforced concrete (RC) elements reducing both their strength capacity and ductility. Especially in seismic prone areas, degradation cyclic behavior corroded RC is more intense, limiting service life structures leading to premature failures. In present paper, order study degraded embedded (in concrete) under ...

The research progress surrounding second-phase particle-induced corrosion has been expounded through extensive work, including local (pitting corrosion, crevice stress corrosion) of Al2O3, (RE)-AlO3, CaS, MnS, NbC, and other particles in microalloyed high-strength rebars. By summarizing the mechanism these rebars, this review further explores fact that play an inducing role which guiding signif...

Pitting corrosion is a complex mechanism and has been found in the inner sections of offshore wind structures where standards at time indicated that those were water tight therefore free from corrosion. Pits propagate grow size this can have serious implications for structural integrity structure by reducing fatigue life but also under some conditions changing to crack whereby damage be acceler...

The effect of Cu2+ in bulk solution on pitting corrosion resistance extra-high-purity type 316 stainless-steel was investigated. Pitting occurred 0.1 M NaCl-1 mM CuCl2, whereas not initiated NaCl. Although deposition the surface regardless a potential region had no influence passive film formation. decrease CuCl2 resulted from deposited Cu or compound and continuous supply surface.

2024 T3 is one of aluminium alloys which are widely used in the aircraft structures. Anodizing of alluminium alloy in tartaric-sulphuric acid (TSA) electrolyte is developed to obtain more environmentally-friendly process and to produce anodize layer with better corrosion resistance. In this research work, the influences of anodizing parameters of Al 2024 T3 in TSA on the thickness, weight and c...

The structure of a titanium nitride film coated by arc ion plating on a Ni-50Ti shape memory alloy was characterized by X-ray photoelectron spectroscopy (XPS). The corrosion behavior of the titanium nitride-coated Ni-50Ti alloy was examined in 0.9% NaCl solution by potentiodynamic polarization measurements and a polarization resistance method. XPS spectra showed that the titanium nitride film c...

An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be expected from the Faraday law with the use of the expected valence of the formed ions. Mechanical disintegration, gas bubble blocking, hydrogen e...

We report a detailed study of the morphology of pits formed by corrosion of aluminum thin films using an in-plane light scattering technique. We show that the corrosion front of the Al thin film can be treated as a quasi-two-level random rough surface. Based on an elastic diffraction theory, we are able to determine the average depth, the area, and the density of pits, as well as the fractal di...
