Corrosion control can be initiated in many ways and may involve either a reduction in corrosion rate or corrosion prevention. Electrolytic corrosion can be prevented by removing a corrosion parameter such as oxygen, moisture or the soluble ions that form the electrolyte. Removing moisture will prevent the formation of an electrolyte solution and is normally cheaper and technically less challeng...

Because of the existence of corrosion media such as chlorine, serious corrosion attacks ships, offshore and marine structure. Scholars worldwide have been long committed to the research of marine corrosion and development of anti-corrosion agents, and have achieved remarkable results. But so far, the conventional ocean coating inevitably makes microholes or microcracks between the additive and ...

A review is provided about the current research on magnesium/magnesium alloys corrosion in the industry. Except for reviewing the kinds of corrosion on galvanic corrosion, stress corrosion, and corrosion fatigue, its corresponding mechanisms are also explained, such as the influence of metallurgical factors, and environmental factors. Furthermore, the protection of magnesium/magnesium alloys co...

The increase in CO2 concentrations and global warming will increase the carbonation depth of concrete. Furthermore, temperature rise will increase the rate of corrosion of steel rebar after carbonation. On the other hand, compared with normal concrete, high volume fly ash (HVFA) concrete is more vulnerable to carbonation-induced corrosion. Carbonation durability design with climate change is cr...

Complex numerical models and simulations from the microscale to the macroscale have been developed for the corrosion of aluminium (Al) alloys typically used for aircraft construction, such as AA2024. The main motivation for developing the corrosion models and simulations is to make significant technical advancements in the fields of aircraft design (using current and new materials), surface pro...

The wind turbine foundation serves as a permanent construction in the harsh marine corrosive environment, its anticorrosion design is essential to the safe use of the wind turbine structure. At present, there is a significant controversy over the local corrosion mechanism (such as pitting corrosion, and crevice corrosion) and its diffusion mechanism in the academic circle. In the paper, the Far...

Government retains for itself, and others acting on behalf, a paid-up, nonexclusive, irrevocable worldwide license and said article to reproduce, prepare derivative works, distribute copies to the public, and perform publicly and display publicly, by or on behalf of the Government. The purposes of this project are to (1) minimize the environmental discharge of hydrocarbons and treatment chemica...

In this paper, the fractal dimensions are proposed for characterizing the optical fiber corrosion sensors, which is applied to measure the steel corrosion based on Fe-C alloy film. Because corrosion was a complex random phenomenon and the corrosion surface of Fe-C alloy film of the optical fiber corrosion sensor possessed fractal characteristics, the image fractal dimensions is as a quantitativ...

A novel Mannich-modified imidazoline (MMI) as cationic emulsifier was synthesised for corrosion harm reduction, through three steps — acylation, cyclization, and Mannich reaction. The surface activity was characterized by determination of surface tensions and critical micelle concentration (CMC). The corrosion inhibition performance of five types of steels in the simulated corrosion solution in...
