MONITORING THE BEHAVIOUR OF KERA N ALLOY TO CORROSION IN AFNOR ARTIFICIAL SALIVA
Corrosion consists in the degradation of a material under the chemical or
electrochemical action of the environment in which it is placed. The investigations carried out aimed
at showing the behaviour of KERA N (Eisenbacher Dental – Waren ED GmbH, Germany) alloy to
corrosion in AFNOR artificial saliva. In this study we used the linear polarization method at different
scanning speeds and the cyclical polarization method. The corrosion potentials for Kera N alloy
under study vary depending on the scanning speed of the potential between -927.5mV and -516 mV.
From the cyclical polarization tests we noticed that the Ni-based alloy, Kera N (Eisenbacher Dental
– Waren ED GmbH, Germany) shows a generalized corrosion type without the tendency to form
pitting type corrosion
