A review of plant extracts as green corrosion inhibitors for CO2 corrosion of carbon steel

open access: yesnpj Materials Degradation, 2022
The use of corrosion inhibitors is a cost-effective corrosion mitigation strategy for carbon steel. There is an increased focus on developing and using low-cost, biodegradable and environmentally friendly inhibitor formulations. Plant-based extracts have

Evading strength-corrosion tradeoff in Mg alloys via dense ultrafine twins

open access: yesNature Communications, 2021
Conventional ultrafine-grains can generate high strength in Mg alloys, but significant tradeoff of corrosion resistance due to inclusion of a large number of non-equilibrium grain boundaries.

Quantitative measures of corrosion and prevention: application to corrosion in agriculture [PDF]

open access: yes, 1987
The corrosion protection factor (c.p.f.) and the corrosion condition (c.c.) are simple instruments for the study and evaluation of the contribution and efficiency of several methods of corrosion prevention and control. The application of c.p.f.

Atmospheric Corrosion [PDF]

open access: yesProceedings of the National Academy of Sciences, 1974
A model of electrolytic corrosion is developed. It is shown that electrically conducting channels threading through the oxide layer and connecting anodic and cathodic areas, obey the equation for a reactant being catalyzed by its product. The resulting autocatalytic equation is compared with available experimental data and found to be widely applicable

A fresh look at depolarisation criteria for cathodic protection of steel reinforcement in concrete [PDF]

open access: yesMATEC Web of Conferences, 2019
Criteria for the successful application of cathodic protection (CP) for steel reinforced concrete have been fixed for decades and form part of ISO EN12696. The most used criterion is the achievement of 100 mV depolarization over a period not exceeding 24

Carbonation and Corrosion Problems in Reinforced Concrete Structures

open access: yesBuildings, 2022
Reinforced concrete (RC) has been commonly used as a construction material for decades due to its high compressive strength and moderate tensile strength. However, these two properties of RC are frequently hampered by degradation.
