Growth Kinetics And Breakdown Of Passive Films On Rebar Electrodes In Simulated Cement Pore Solution, Wei Chu, Yuanxiang Shi, Baoming Wei
Journal of Electrochemistry
The growth kinetics and breakdown of passive films on REBAR electrodes insimulated cement solution(pH=12.5 and 13.8)have been investigated using in situphotoelectrochemical methods and potential step method. The results show that there are two mainstages in the growth of the film ,with two rate functions characterized by linear relation between thefilm thickness and the direct logarithm of time. There is a sign in laser-scanning photoelectrochemicalmicroscopic image just before the passive film breaks down. The addition of inhibitor NaNO_2changesthe growth kinetics and thickness of the film ,and therefore improves the resistance of pitting corrosioninduced by chloride.

Cyclic Voltammetric Calorimetry Studying The Deposition Of Copper Of Pt Electrodes, Yongchun Zhu, Robin H J Clark
Journal of Electrochemistry
In the present paper,cyclic voltammetric calorimetry has been used to study thedeposition of copper on platinum electrode from LiClO_4 aqueous solution. Cyclic voltammetricthermogram and cyclic voltammetric differential thermogram show that the deposition of copper on theelectrode is an exothermal process with a strong interaction between copper and platinum layer(-3227.0 kJ /mol).The electrochemical oxidation of the deposited copper is composed of twoprocesses :an endothermal activation process with 747.0 kJ/mol of activation enthalpy,and anexothermal oxidation reaction with-189.9 kJ/mol of the reaction enthalpy, which are accord withthe data from the theoritical estimation and thermodynamic handbook respectively.
