Abstract
In the present study the fatigue strength of the experimental alloy Ti30Ta was evaluated after the surface modification using alkaline and heat treatment. The alloy was obtained from the fusion of the elements in a voltaic arc furnace with inert atmosphere (argon gas), forged and heat treated. The specimens were machined in accordance with ASTM E466 for the fatigue test. Surface modification was performed by alkaline treatment in 1.5 M NaOH solution and heat treatment. The fatigue test was performed under modified surface conditions and substrate. The characterization of the alloy used techniques of optical microscopy, scanning electron microscopy, X-ray diffraction, roughness and contact angle. The results suggest that the surface modification did not influence the mechanical performance of the Ti30Ta alloy.
