Characteristics of Cathodic Reactions in BaCl2-NaCl Melts Containing AlF3 Components

Electrochemical Deposition of Aluminum from NaCl-AlCl3 Melts

Elec t rochemica l depos i t ion of a l u m i n u m from NaA1C14 melts sa turated wi th NaC1 onto a glassy carbon e lec t rode at 175~ has been s tudied by vo l tammetry , ch ronoamperomet ry , and cons tant current deposi t ion. The depos i t ion of alumin u m was found to proceed via a nuc lea t ion/growth mechan i sm, and the nuc lea t ion process was found to be progressive. The morpho logy...

Hot Corrosion of Ti-Based Intermetallics with Coatings in NaCl+ (Na,K)2SO4 Melts at 750oC

In this study, the hot corrosion of TiAl, TiAlNb, and Ti3AlNb intermetallics with or without enamel coating and sputtered TiAlCr coating in (Na, K)2SO4 + NaCl melts at 750oC is investigated. The interfacial reaction between enamel and those alloys during hot corrosion has also been evaluated. The results indicate that severe corrosion of bare alloys occurs due to the self catalysis chlorination...

The Role of Cathodic Poisons on the Stress Corrosion Cracking of Zircaloy- 2 in Methanolic Solution Containing 0.4vol.% Hydrochloric Acid

Voltammetric characteristics of miconazole and its cathodic stripping voltammetric determination.

Miconazole is reduced at mercury electrode above pH 6 involving organometallic compound formation, responsible for an anomalous polarographic behavior. The electrodic process presents a large contribution of the adsorption effects. The drug can be determined by cathodic stripping voltammetry from 8.0 x 10(-8) to 1, 5 x 10(-6) molL-1 in Britton-Robinson buffer pH 8.0, when pre-accumulated for 30...
