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 ...

The corrosion behavior of both tin-plated carbon steel and aluminum (Al 1100) in NaCl solutions were studied using electrochemical impedance spectroscopy (EIS). The study objectives were to compare their corrosion behavior in concentrated brine solution, establish the equivalent electrical circuit diagrams of their corrosion phenomena, and consequently develop steady-state corrosion models for ...

High purity Flibe was prepared for corrosion study. Fundamental corrosion experiments in static condition were performed on the structural material for Flibe blanket and Material Research Loop, which is non-isothermal forced convection loop simulating the blanket condition. Corrosion rate for the structural materials in static condition was estimated as small as 0.83-5.4 μm/yr in the high purit...

Borated water leakage through spent fuel pools (SFPs) at pressurized water reactors is a concern because it could cause corrosion of reinforcement steel in the concrete structure and compromise the integrity of the structure. Because corrosion rate of carbon steel in concrete in the presence of boric acid is lacking in published literature and available data are equivocal on the effect of boric...

austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. in the case of single pass welding of thinner sections of this alloy, pulsed current micro plasma arc welding (pcmpaw) has been found bene...

In the present paper the corrosion properties of structured sheet metals were investigated. The aim of this work is to determinate the influence of the structuring process on the corrosion resistance of sheet metals. For this purpose, these sheets were examined by accelerated tests in corrosion chamber. The investigation was carried out using salt spray test. The experiment was conducted for th...

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...

The corrosion resistance of type 304L and 316 austenitic stainless steels in 2M H2SO4 at 0-1.5%NaCl concentrations was studied through potentiodynamic polarization technique and optical microscopy analysis. The corrosion rate, pitting potential, passivation potential and surface morphology of both steel where significantly altered by the Clion concentration, alloy composition and metallurgical ...

The paper deals with the corrosion behavior of stainless steels as candidate materials for biofuel production plants by liquefaction process of the sorted organic fraction of municipal solid waste. Corrosion tests were carried out on AISI 316L and AISI 304L stainless steels at 250 °C in a batch reactor during conversion of raw material to bio-oil (biofuel precursor), by exposing specimens eithe...

Microbiologically influenced corrosion (MC) of steel has been attributed to the activity of biofilms that include anaerobic microorganisms such as iron-respiring bacteria, yet the mechanisms by which these organisms influence corrosion have been unclear. To study this process, we generated mutants of the iron-respiring bacterium Shewanella oneidensis strain MR-1 that were defective in biofilm f...
