A cyclic wet/dry accelerated corrosion test was used to compare the corrosion behavior of medium-Mn steel and Q345 steel. In terms of scanning electron microscope (SEM), using X-ray diffraction (XRD), electron probe microanalysis (EPMA), X-ray photoelectron spectroscopy (XPS), and analysis of the corrosion process, the results showed that the medium-Mn steel did not exhibit higher corrosion res...

The corrosion of reinforcements induced by chloride has resulted to be one of the most frequent causes of their premature damage. Most corrosion sensors were designed to monitor corrosion state in concrete, such as Anode-Ladder-System and Corrowatch System, which are widely used to monitor chloride ingress in marine concrete. However, the monitoring principle of these corrosion sensors is based...

Introduction Reliable estimates indicate that corrosion of metals costs the US economy almost $300 billion per year or about 4% of the GNP. Corrosion is a pervasive problem that affects almost all sectors of the economy including transportation (bridges, automobiles, aircraft, ships, pipelines, etc.), energy (power plants, petrochemical industries etc.) and defense (naval applications, aging ai...

E M A I L : a m p t i a c @ i i t r i . o rg Introduction The Air Force Corrosion Prevention and Control Office, located at Robins AFB, GA, and operated by the Air Force Research Laboratories’ Materials Directorate recently achieved a major milestone in demonstrating an aircraft corrosion prediction program. The AF Corrosion Prevention and Control Office accomplishes its mission by ensuring Air...

the traditional fuzzy operators, such as t-norms, t-conorms and averaging operators have been used for soil suitability evaluation to aggregate criteria as an overall suitability index. however, such operators do not account for the degree of compensation common to human aggregation criteria, especially in the presence of conflicting criteria. fuzzy integrals are powerful and flexible aggregati...

A Blast furnace is an investment in the future. It is necessary that there is the proper dimensioning of all the equipment, systems and components as well as incorporation of technologies which assure the desired production and quality so that improved performance of the blast furnace can be achieved. Gas is one of the major resources of nature. Gas distribution across any part is processed by ...

This study presents and implements a corrosion-monitoring wireless sensor platform, EPS (Events as Power Source), which monitors the corrosion events in reinforced concrete (RC) structures, while being powered by the micro-energy released from the corrosion process. In EPS, the proposed corrosion-sensing device serves both as the signal source for identifying corrosion and as the power source f...

Corrosion is one of the main causes affecting durability of structures. Corrosion effects on structures cannot be ignored and replaced. To understand the performance of structures there is a need to study the rate at which different corrosion levels occur. Hence the present investigation has been taken up to study the behaviour of NBS (National Bureau of Standard) beam specimens made up of Ordi...
