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...

The microstructure of the produced has studied and corrosion behaviour assessed in 3.5% NaCl solution. exhibited low porosity, good homogeneity, few defects, distribution reinforcing phase Al matrix. No secondary intermetallic phases formed while inte...

Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...

The stability of an electrodeposited nanocrystalline Ni-based alloy coating in a H₂S/CO₂ environment was investigated by electrochemical measurements, weight loss method, and surface characterization. The results showed that both the cathodic and anodic processes of the Ni-based alloy coating were simultaneously suppressed, displaying a dramatic decrease of the corrosion current density. The co...

1 ide (mineral name: eskolaite) for the glass tank's lining. Due to its low solubility in the glass melt, the corrosion resistance of the fireproof material is remarkably improved. Though, a high commodity price and an extensive preparation and processing causes a high price. That condition poses the question, how high or low the eskolaite content has to be, depending on its position in the gla...

In the present work, TiZrHfNbFex (x = 0, 0.25, 0.5, 0.75, 1, 1.5, and 2, molar ratio) refractory high-entropy alloys (HEAs) were developed. The microstructure, mechanical properties, corrosion wear resistance of Ti-Zr-Hf-Nb-Fe HEAs investigated. exhibited a dendrite structure with body-centered-cubic (BCC) + Laves phases. Among them, TiZrHfNbFe0.5 HEA displayed good comprehensive properties har...
