Influence of La-Content and Microstructure on the Corrosion Properties of a New Free Machining Titanium Alloy
Abstract
<jats:p>A new titanium alloy was developed at the Technische Universität Braunschweig by alloying the standard Ti6Al4V with lanthanum. Lanthanum contents between 0.9% and 2.8% lead to improved machinability by reducing the chip length up to a factor of 100. The microstructure of the alloys depends on the sample treatment. Cast alloys have a martensitic structure whereas compressed and annealed ones show a Widmannstätten structure.The corrosion properties of these new alloys were investigated by electrochemical methods and standard corrosion tests. Investigations with potentiodynamic polarization showed that lanthanum containing alloys exhibited an active passive transition near the Eoc in chloride solutions, which is attributed to the dissolution of lanthanum. All alloys showed a similar behavior in artificial saliva and sulfuric acid. Electrochemical impedance spectroscopy (EIS) measurements confirmed the results of the other methods.</jats:p>
