An anisotropic Nd-Fe-B magnet was prepared by the spark plasma sintering (SPS) technique. A magnet with the same composition was produced using the conventional sintering method for comparison. The oxidation behavior in oxidizing environments for both magnets was studied. The microstructure and com ... [Corrosion 66 055004 (2010)] published Sat May 01, 2010.

An overview is given of the key role for reduction of hydrogen ions and water in determining the local chemistry and electrochemistry in crevices and cracks. Thus, the ability to cathodically protect long, tight crevices and cracks is explained on the basis of depletion of oxygen but also on the sl ...

Potential-pH (Pourbaix) diagrams are used as road maps for aiding in predicting the most stable states of a metal, its corrosion products, and its associated ions in an aqueous solution. It is presented in a plot of equilibrium potential vs. hydrogen ion activity. Organic ions, including those of b ... [Corrosion 66 055003 (2010)] published Sat May 01, 2010.

A multi-electrode test method has been developed to assess the performance of corrosion inhibitors under sand deposits for oil and gas applications. The electrode array is mounted in a cup under a layer of sand and coupled to an external carbon steel electrode in such a way that the galvanic corros ...

The three key aspects of the top-of-the-line corrosion process are condensation, chemical speciation, and corrosion. The focus of this study is on the condensate speciation through a thermodynamic approach. Specifically, the goal of this study was to determine the concentration of acetic acid in th ...

Gas transmission pipeline corrosion commences when coatings disbond, exposing the steel to groundwater. When this occurs, a number of anaerobic and aerobic corrosion scenarios can be envisaged. The initial nominally anaerobic corrosion period has been investigated by applying a combination of elect ... [Corrosion 66 045001 (2010)] published Thu Apr 01, 2010.

The inhibition effects of 4-phenyl-3-thiosemicarbazide (PT) on the corrosion of aluminum in 0.1 M hydrochloride acid (HCl) solution at 298 K to 343 K using potentiodynamic polarization have been investigated. The adsorption of the inhibitor on the aluminum surface was found to comply with the Langm ... [Corrosion 66 045006 (2010)] published Thu Apr 01, 2010.

Corrosion and stress corrosion cracking of carbon steel in bio-fuels are a concern with the increase in the usage of ethanol as an alternate fuel. Electrochemical studies in highly resistive electrolytes (e.g., ethanol) traditionally have been conducted with the addition of a supporting electrolyte ...

Paint is applied to effectively protect steel structures from corrosion. Coatings act as a barrier to a corrosive solution and transfer the electrical charge from the corrosive solution to the metal underneath the coating. The diffusion path of coatings may vary owing to the composition of the coat ... [Corrosion 66 045004 (2010)] published Thu Apr 01, 2010.
