Resumen

The systematic evaluation of the electrochemical changes induced in relevant materials by LSP treatment has been envisaged. Analysis of cyclic polarization curves with clear identification of corrosion parameters (Ecorr, Icorr, Mcorr, Ep, Ip) has been succesfully performed for Al2024-T351 and AISI 316L steel. Electrochemical Impedance Spectroscopy (EIS) has been used in order to correlate the observed electrochemical behaviour (even at long timescales) with surface modifications induced by the LSP treatment, especially roughness and elemental chemical composition. A good physico-chemical process understanding has been gained in the case of Al2024-T351 and AISI 316L steel. Work has been initiated for other key materials with a more complex behaviour (i.e. Ti6Al4V).The development of a systematic assessment capability for the corrosion susceptibility modification effects of the LSP technique is under way.
