Lanthanide salts as
corrosion inhibitors of aluminium alloys
A variety of techniques are employed to obtain information about the corrosion mechanism of the alloys and the anticorrosive effects of lanthanide inhibitors. The best performance has been obtained using CeCl3 when the corrosive media was NaCl solutions. |

Application
of waveles to electrochemical noise
It is a mathematical tool developed recently which allows a simultaneous analysis in frequency and time domain. Its application to ENM is especially useful to study non-stationary signals and to filter noise. |
 |
Automatic detection of EN transients
An algorithm has been developed based on wavelet transform, which enable to detect the time of occurence of electrochemical noise transients and clasify them with regard to their intensity and scale. |

Study of the influence of
Surface finishing
An electrochemical noise study has been performed about the behaviour of AA5083 aluminium alloy in 3.5% NaCl solution when the surface of the coupon is polished at 80 and 1200 grits. |

Non contaminant coatings
for steels and galvanised steel protection
This project has been started recently to formulate and test new water-borne coatings with very low contents of volatile organic components and with non-toxic pigments when they are submitted to the action of the atmospheric agents. |

Multimedia software for corrosion
teaching
This software, which is presented as an alternative to in-situ practices, let the students compare different types of corrosion processes and familiarize with the basic methodology applied to characterise those alloys. |
