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 [...]

Morphological variations on titanium by AC anodizing

Diamanti M.V., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Besides the widely investigated photoinduced properties of its oxides, a primary branch of application of anodized titanium is the production of biomedical implants, where a controlled roughness can lead to improvements in cell adhesion and [...]

Thermal Cycling of 300 nm Buried Damascene Copper Interconnect Lines by Joule Heating

Read D.T., Geiss R.H., National Institute of Standards and Technology, US

We report tests of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric to failure under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured [...]
