Mechanical properties and microstructure of Nb-Ta-Re, Nb-Re, Nb-Pd, and Nb-Pt alloys were studied by nano-indentation measurements and X-ray diffraction. Corrosion behavior was compared by electrochemical methods, including open circuit potential measurement, potentiodynamic, and electrochemical impedance spectroscopy.
Dental implants are exposed to a wide range of pH values of saliva and different concentrations of fluoride. In this study, the effects of fluoride concentration and pH value on the corrosion behavior of Nb-10Ta-1Re and Ti-6Al-4V alloys in artificial saliva at 37°C were investigated by electrochemical measurements.
The aim of this work is to analyze the role of corrosion management in prevention of corrosion accidents related primarily to safety of personnel and the environment. This is achieved by anti-corrosion measures, corrosion monitoring, regular inspection, study of each accident, implementation of meetings, publications, education, and knowledge transfer.
