Corrosion inhibition of stainless steel by protective coating

SurPASS™3 determines the zeta potential at the surface of a macroscopic solid in contact with an aqueous solution.

Our industrialised world with its manifold applications under extreme conditions requires high-tech materials.

Corrosion inhibition of stainless steel

Stainless steel is one of those materials employed in many industrial fields with rough environments and operating conditions, e.g., for marine and petrochemical applications such as the construction of ships or stainless steel pipes for oil production. In order to extend the lifetime of stainless steel components upon exposure to seawater or corrosive media, different protective coatings are applied.

The zeta potential is a valuable parameter to understand corrosion phenomena and the effect of coatings. It describes the chemistry and the conductivity of the surface simultaneously.
