Study on Ni-Cr-Mo Dental Alloy Subjected to Electrocorrosion in Artificial Saliva

The investigations conducted aimed at determining the microstructural and chemical modifications produced in a Ni-Cr-Mo alloy following electrocorrosion in Afnor artificial saliva by using SEM electronic microscopy and EDS chemical analysis. By 2D and 3D microscopy and by qualitative determinations of the luminous variation we could notice the effects of electrocorrosion tests on the surface of the metallic material, and by EDAX qualitative and quantitative determinations (Point, Line and Mapping modes) of the surface chemical composition we could determine the chemical modifications produced following the corrosion tests.
