Degree of sensitization and pitting corrosion potential of a supermartensitic stainless steel weldment were measured and compared. An improvement in the degree of sensitization and in the pitting corrosion potential, from the base metal to the weld metal, was found in the electron beam weldment. Th ...

Coupled multielectrode array sensors (CMAS) have been used for real-time monitoring of corrosion, particularly localized corrosion. The internal anodic current on the most anodic electrode in a CMAS was evaluated for aluminum and carbon steel in simulated seawater and dilute hydrochloric acid (HCl) ...

Corrosion inhibition of the self-assembled monolayer (SAM) of 1,2,3-Benzotriazole (BTAH) on virgin and sulfide-covered (tarnished) copper surfaces was studied using impedance, scanning electron microscopy, and Raman spectroscopy. SAM on preexisting sulfide film develops a more improved protection t ... [Corrosion 66, 115002 (2010)] published Mon Nov 01, 2010.

The influence of organic compounds on the corrosion of stainless steel in 0.5 M sulfuric acid (H2SO4) was investigated using weight-loss and potentiodynamic polarization techniques, as well as open-cirucuit potential (OCP) measurements. The nature of the film formed and the adsorption mechanism, as ... [Corrosion 66, 115003 (2010)] published Mon Nov 01, 2010.

The electrochemical corrosion and passivation behavior of four selected tin-silver alloys, xSn-Ag (x = 26, 50, 70, and 96.5 wt%) (II through V), in addition to their pure metallic components, Ag(I) and Sn(VI), were investigated in aqueous sodium hydroxide (NaOH) solution. The techniques used are li ... [Corrosion 66, 115001 (2010)] published Mon Nov 01, 2010.

The corrosion protection of cerium-based conversion coatings (CeCC) formed on AZ91D magnesium alloy has been studied using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and salt fog testing. The effect of acid (sulfuric acid [H2SO4]) and alkaline (sodium c ... [Corrosion 66, 115006 (2010)] published Mon Nov 01, 2010.
