【 摘 要 】
The goal of this study consists in the determination of structural modifications produced in a non-noble alloy intended for metal components of the skeletonized removable partial dentures following electrochemical corrosion in artificial saliva. The behavior to electrochemical corrosion was shown by the microstructural and chemical analysis by means of an electron scanning microscope fitted with an EDAX electron detector. We noticed that on the analyzed surface of Co-Cr-Mo alloy (Remanium GM 800, Dentaurum) that the Co and Mo elements lost their initial mass percentage, whereas others like Si increased their mass percentage with a very small quantity, a fact indicating the corrosion of Co and Mo elements and a better resistance of silicon. Following the determinations made, we may affirm that Co-Cr-Mo alloy (Remanium GM 800, Dentaurum) has a behavior to electrochemical corrosion in artificial saliva of generalized type and preferential by phases, with oxidization on the entire surface of the material and the formation of a superficial corrosion layer on the phase of matrix type.
