WHY

Examples of corrosion are found in many industrial applications ranging from aeronautical, automotive, naval, and the construction industry over home appliances, water systems, pipelines, and ‘bio’ applications. Corrosion phenomena can be significantly accelerated by the simultaneous occurrence of a mechanical load on the surface: the formation of cracks and surface defects, along with surface strain and stress fields lead to faster diffusion of corrosive ions or the destruction of protective layers (depassivation). Thus there is a need to understand the synergy between wear and corrosion.

HOW

An electrochemical cell was implemented in the Basalt-N2 tribometer. This setup allows for a fast and accurate measurement of the frictional behaviour of materials under various environments, whereas it is flexible and versatile in loading range (depending on the selecting cantilevers, load can range from 0.2 mN up to 100 N) and different contact geometries (point, line, area contacts) can  be used. In this way both the tribological and electrochemical properties can be monitored and correlated.
