The atmospheric corrosion of weathering steels varies as a function geographic zone, season, and other environmental variables related to that region which the experiments have been done. Meanwhile, rusting is continuous process, it main product corrosion. current study investigates effects rust on steel in localized Digha, sea resort West Bengal, India. investigations performed by purposely ac...

Anodic oxide fabricated by anodizing has been widely used for nanostructural engineering, but the nanomorphology is limited to only two oxides: anodic barrier and porous oxides. Therefore, the discovery of an additional anodic oxide with a unique nanofeature would expand the applicability of anodizing. Here we demonstrate the fabrication of a third-generation anodic oxide, specifically, anodic ...

In ships, materials of different electrochemical potentials the steel of the hull and the bronze of the propellers coexist. Once bathed in the sea water and electrically connected by the internal structures, phenomena of corrosion induced by galvanic coupling appear. These phenomena create currents in the water around the ship and induce, in the conducting sea water, a static electric field cal...

aluminum anodes have been widely used in the cathodic protection of marine structures. however there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. addition of alloying elements such as zn and in not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra melt...

The study highlights the corrosion behavior of untreated and treated tantalum with addition trimanganese tetraoxide (Mn3O4) nanoparticles in simulated inflammatory media. anodic layer was produced on pure by anodization electrolytes composed ammonium fluoride, ethylene glycol, water. Nanoparticles were deposited uniformly surface anodized electrophoretic deposition (EPD) method. results reveale...

A practical anodic and cathodic curve intersection model, which consisted of an apparent anodic curve and an imaginary cathodic line, was proposed to explain multiple corrosion potentials occurred in potentiodynamic polarization curves of Fe-based glassy alloys in alkaline solution. The apparent anodic curve was selected from the measured anodic curves. The imaginary cathodic line was obtained ...
