Design of Experiment Based Prediction of Passivity Breakdown Potential for 304L Stainless Steel

Azimi Dastgerdi A., Bellè U., Brenna A., Ormellese M., Pedeferri M., Bolzoni F., Politecnico di Milano, IT

Stainless steels usually have a good corrosion resistance because of the protective passive film that forms on the surface, however they are prone to localized corrosion (pitting and crevice) due to the breakdown of passive [...]

Enhancement of pure titanium localized corrosion resistance by chemical oxidation

Prando D., Brenna A., Diamanti M.V., Ormellese M., Pedeferri M.P., Politecnico di Milano, IT

Titanium and its alloys are widely appreciated for their high corrosion resistance in environments that are critical even for high-end stainless steel (duplex UNS S31803 and UNS S32750), such as concentrated chlorides [1]. This resistance [...]

A proposal of AC corrosion mechanism in cathodic protection

Brenna A., Diamanti M.V., Lazzari L., Ormellese M., Politecnico di Milano, IT

The research proposes an electrochemical mechanism of AC-corrosion in CP condition. Electrochemical tests were carried out on carbon steel in simulated soil conditions to identify AC corrosion risk related parameters during cathodic polarization, like AC [...]
