The proposed work will combine chemical kinetics and hydrodynamics in target and test-loop lead-bismuth eutectic (LBE) systems to model system corrosion effects. This approach will result in a predicative tool that can be validated with corrosion test data, used to systematically design tests and interpret the results, and provide guidance for optimization in LBE system designs. The task includ...

Wind erosion (or aeolian corrosion) is one of the most relevant causes weathering and degradation which has affected building surfaces in Cultural Heritage. The effect depends on wind strength, impact particles transported their size characteristics affected. This aspect very important for historical buildings constructed by using limestone as Lecce stone (LS). LS an extraordinary ability to be...

Under badly environmental conditions as well as complex loads, corrosion of embedded reinforcing steel bars in concrete is common for reinforced concrete (RC) structures. Fatigue of corrosion reinforcing steel bars is a key problem for old RC bridges. To assess the residual fatigue life of aged existing RC bridges, the most new study information on fatigue of natural corrosion reinforcement is ...

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...

The corrosion of reinforcing steel in concrete has been reported as one the main durability problems reinforced (RC) structures exposed to chloride, carbonation or both. To investigate structural performances RC subjected corrosive exposure, rebars embedded is accelerated induce a targeted degree reinforcement short time duration. Several earlier researchers have attempted develop setup bars st...

oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

This paper reviews the available literature relating to the emerging research into the performance of coatings under combined wear and corrosion conditions. Understanding how coatings perform under these tribo-corrosion conditions is essential if the service life of equipment is to be predicted and to allow service life to be extended. Therefore, the tribo-corrosion performance of coatings depo...

Abstract In a freshwater environment, accelerated corrosion of carbon and stainless steels is frequently observed. Here, an immersion study was conducted using nine types in pool for 22 mo. Accelerated observed Cr-containing cast iron, whereas no visible steels, even after Microbial community analysis showed that, general corrosion, Fe(II)-oxidizing bacteria were enriched the early phase, Fe(II...
