A TCP–TCL model is established to describe the relationship between the thickness of the corrosion-filled paste (CP) and that of the corrosion layer (CL). This model can describe the phenomenon that the corrosion filling in the concrete pores and accumulating at the steel/concrete interface occur synchronously. Based on the TCP–TCL model, a corrosion-induced concrete cracking model, which can q...

The self-assembled monolayer (SAM) was prepared using octadecyl trichlorosilane (OTS) in distilled solution on the copper surface. The effect of inhibitor concentration on the rate of inhibition efficiency and corrosion rate in corrosion medium on copper by using polarization curves, electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM) was studied. The results showed...

Corrosion is all around us and can affect our lives in many ways, because metals are so widely used in our world. Corrosion-related failures in the industries often result in catastrophic failures. Corrosion is not only dangerous, but costly. The cost of corrosion is estimated to be huge and protecting or reducing corrosion is one of the most important problems in engineering. Many attempts hav...

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...

Lithium is known to accelerate the corrosion of zirconium alloys in light water reactor conditions. Identifying mechanism by which this occurs will allow alloying additions and alternative coolant chemistries be proposed with aim improved performance. Accommodation mechanisms for Li bulk ZrO2 were investigated using density functional theory (DFT). Defects including oxygen vacancies along lithi...

The corrosion of geotechnical prestressed anchor rods directly affects the safety structure engineering. To this end, an experimental device for measuring stress loss was developed, which used to study a under corrosive environment, obtain change curve structure, and analyze influence environment on in coastal areas. final results show that degree damage bolts determined by cross effect stress,...

The heterogeneous structure of Al alloys renders them susceptible to localized corrosion due to the different electrochemical properties existing in the Al-rich solid solution matrix and secondary phase particles. The galvanic interactions between these two phases can result in pit formation either through dissolution of the particles or corrosion of the matrix adjacent to the particles. This d...
