description

Abstract Tribocorrosion is of complex nature as it involves multiscale interactions between mechanical, (electro-)chemical, physical, and material factors. A methodology based on the use of the Pearson’s correlation matrix and local techniques is described here to analyze interactions between these factors. The most influent experimental parameters selected for tribocorrosion tests on the surface/subsurface characteristics and on the corrosion parameters are identified. Correlations between surface/subsurface and corrosion parameters are also analyzed to propose criteria and to understand basic mechanisms of tribocorrosion. This methodology is particularly useful in the case of multiphase materials and engineering systems with complex structures.
