The Use of Electrochemical Techniques for the Characterization of the Corrosion Behavior of Sol–Gel-Coated Metals

The object of the present work is the characterization of the corrosion behavior of Al-5%SiC nanocomposites prepared by mechanical alloying and the hot pressing method. Al/SiC metal matrix composite (MMCp) powder with volume fraction of 5% SiC was synthesized by high-energy milling of the blended micro component powder. The mechanically mixed nanocomposite powder was consolidated into bulk compacts using hot pressing at 1 GPa pressure for thirty seconds at three different temperatures of 440, 480 and 520°C. The microstructure was investigated by Secondary electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The corrosion behavior of the coating was evaluated using electrochemical techniques such as potansiodynamic polarization and EIS. It was found that the corrosion resistance of Al-5%SiC nanocomposite when hot pressed at 480°C, in 3.5% NaCl solution was higher than pure Al and Al-SiC nanocomposite that had been hot pressed at other temperatures.

Diffusion Studies

AbstractIonically conducting materials containing PEO were prepared from telechelic di(methyl-diethoxy-silane) PEO, synthesized by the hydrosilylation of telechelic diallyl-PEO with methyldiethoxysilane. The network is obtained by the usual sol-gel chemistry. Then, it is filled with LiClO4 by diffusion of the salt and further drying. A comparison is made with the same kind of materials crosslinked using urethane chemistry. Diffusion studies show that the diffusion coefficient of solvent is similar for both types of materials, whilst the ionic conductivity is higher for the networks crosslinked with siloxane bonds. An experiment of diffusion of LiClO4 without solvent showed that this salt has a diffusion coefficient of the order of 2.10-8 cm2.sec-1 at 34°C. The conductivity calculated from this determination is compatible with the mechanism of lithium cation transport by the diffusion of salt molecules. Elasticity modulus measurements show that the salt aggregates are essentially located within the crosslinks at low concentration, but also in the PEO chains for salt concentrations higher than 1 mol/l.
