Dans le but de decontaminer les radioelements pieges dans le film de zircone, le claquage electrochimique est utilise en milieu acide nitrique pour entrainer la rupture et l’ecaillage du film d’oxyde. On determine les conditions physico-chimiques du claquage et le role joue par les contraintes internes de la couche (par spectroscopie Raman et diverses decoupes). Ce travail est complete par des analyses de surface (MEB) et par des mesures d’impedance afin de determiner l’evolution de la resistance du film lors du claquage.

En milieu aqueux, la dissolution preferentielle du zinc conduit a la formation d’une couche constituee de particules de fer et de sels de zinc. La dissolution coulometrique permet cependant de qualifier le niveau d’alliation du produit. En milieu organique, la corrosion du revetement devient negligeable et la dezincification ne semble pas trop perturber la dissolution.

Research paper thumbnail of Effect of Phosphate Concentration on the Corrosion of Iron in Water—Polyethylene Glycol Mixtures

CORROSION, 2005

Abstract Various electrochemical measurement techniques (polarization, electrochemical impedance ... more Abstract Various electrochemical measurement techniques (polarization, electrochemical impedance spectroscopy [EIS], and electrochemical quartz microbalance [EQCM]) and accelerated corrosion tests were used to show that phosphates can be used as iron corrosion inhibitors in 20% polyethylene glycol (PEG 400) solutions. Their action mechanisms were found to modify the anodic behavior of the iron. In solutions with low-phosphate concentrations (<5 × 10−3 M), an iron oxide film formed, as in the case of aqueous solutions. But this oxide film did not provide protection and pitting occurred. At a phosphate concentration of 5 × 10−3 M or more, the iron was protected but by a film that was different from the one observed in aqueous solutions. A deposit, composed of PEG and phosphates, adsorbed preferentially on the anodic sites of the iron.

The treated materials are designated by B, C, and D. The fusion/cooling treatment modified the microstructural state of the metal. The different microstructural states were revealed by X-ray diffraction. Electrochemical studies of the treated zinc specimens were performed using voltammetry, potentiometry and electrochemical impedance spectroscopy (EIS). Only a significant variation in EIS results was found. The EIS diagrams of the materials varied with immersion times. The variations in low frequency resistance were directly correlated with the microstructural states of the specimens. The results of the study indicate that fusion treatment at 500°C for 60 minutes and cooling by nitrogen to 10 l min-1 is the most suitable for use as a sacrificial anode
