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.
This paper presents the latest laboratory results on iron sulfide dissolver evaluation. The recently developed dissolvers were studied for their dissolving powers using iron sulfide scale solids and the corrosion rate to mild steel at elevated temperature. Based on these results, the technical gaps and future developments for iron sulfide dissolvers are discussed.
