This paper studies the corrosion behavior of B10 copper-nickel alloy in marine environment. Accelerated degradation test under marine environmental conditions was designed and performed based on the accelerated testing principle and the corrosion degradation mechanism. With the prolongation of marine corrosion time, the thickness of Cu₂O film increased gradually. Its corrosion product was Cu₂(O...

Supercritical carbon dioxide (S-CO2) has the advantages of amphoteric liquid and gas, which possesses many unique characteristics, such as good compressibility, high density, solubility, fluidity low viscosity. The Brayton cycle with S-CO2 is considered to have promising applications, especially for power conversion industries. However, corrosion degradation structural materials hinder developm...

Carbon steel remains the most commonly used material in CO 2 – containing oilfield, and other energy applications. Pitting corrosion is a prominent form of attack on carbon steel, linked to formation non protective iron carbonate (FeCO 3 ) films and/or their breakdown. The conditions for local breakdown FeCO , fundamental aspects pitting still not clearly understood; particularly relation evolu...

The corrosion behavior of two stainless steels (316L and 304L) was evaluated using a CO2-loaded aqueous solution 30 wt.% monoethanolamine (MEA) with view to simulating related mechanisms in amine treatment procedures. Corrosion experimentally as function CO2 loading temperature, electrochemical techniques (polarization curves, cyclic polarization, EIS measurement). results reveal that the MEA c...

The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...

For concrete bridge projects in marine environments, attention must be paid to the reinforcement corrosion problems caused by chloride intrusion. As kinds of functional admixtures, which can reduce the reinforcement corrosion rate, corrosion inhibitors are becoming very popular in China in new bridge projects. Corrosion inhibitors cover both inorganic and organic inhibitors. Nitrite is represen...

The effect of oil soluble commercial corrosion inhibitors (OSCI) on the growth of bacteria and its corrosion inhibition efficiency were investigated. Corrosion inhibition efficiency was studied by rotating cage test and the nature of biodegradation of corrosion inhibitor was also analyzed by using FTIR, NMR and GC-MS. This isolate has the capacity to degrade the aromatic and aliphatic hydrocarb...

The corrosion protection factor (c.p.f.) and the corrosion condition (cc.) 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. and cc. to corrosion and prevention in agriculture in The Netherlands is considered in detail. Attention is paid to relations between c.p.f. and c.c., th...
