Electrochemical behavior of titanium in saline environments: The effects of temperature, pH, and microstructure
- Brown Univ., Providence, RI (United States). Div. of Engineering
This research investigates the effects of temperature, pH, degree of salinity, galvanic coupling, microstructure, and composition on the electrochemical behavior of commercially pure titanium in a saline environment. Essentially, the findings establish that increased temperature, altered microstructure, decreased pH, and decreased purity of titanium all serve to increase the corrosion potential and cathodic reaction rate, thus making the metal more susceptible to hydrogen absorption. Further, the data indicate that galvanic coupling with certain metals such as naval brass and stainless steel can anodically polarize titanium, whereas coupling with metals such as aluminum, HY80 steel, and zinc catholically polarizes titanium, thus promoting hydrogen evolution on the titanium surface.
