Abstract Replacing the underground cable steel bracket within service life will increase maintenance cost, so prediction of is aroused. The mechanical properties and atmospheric corrosion carbon are key factors affecting bracket. In this paper, a method brackets considering proposed. First, analyzed by finite element model to determine thickness damage. Based on electrochemical experiments, bas...

Electrochemical post-treatment of ultrathin carbon layer coated cobalt nanoparticles generates a novel electrocatalyst, affording a small overpotential of 333 mV at a current density of 10 mA cm(-2) and a small Tafel slope of ∼58 mV per decade.

The reduction of gaseous oxygen on carbon-supported plat inum electrodes has been studied at 150~ with polarization and potential decay measurements. The electrolyte was either 100 weight percent phosphoric acid or that acid with a fluorinated additive, potassium perfluorohexanesulfonate (C6FI3SO3K). The pseudo-Tafel curves of the overpotential vs. log (iiL/(iL -i)) show a two-slope behavior, p...
