Ti–Ag–Pd alloy with good mechanical properties and high potential for biological applications

Ti-based alloys containing Ag were produced by tilt-casting method and their properties were studied. Even in its as-cast state, Ti(94)Ag(3)Pd(3) showed relatively high tensile properties, good electrochemical behavior, and good biocompatibility.

Descripción
Sumario:Ti-based alloys containing Ag were produced by tilt-casting method and their properties were studied. Even in its as-cast state, Ti(94)Ag(3)Pd(3) showed relatively high tensile properties, good electrochemical behavior, and good biocompatibility. The relatively good mechanical properties of the as-cast α-Ti-type Ti(94)Ag(3)Pd(3) alloy (tensile strength up to 850 MPa and elongation of ~10%) can be explained by its severely deformed, fine crystalline structure. The high biocompatibility of Ti(94)Ag(3)Pd(3) can be explained by the Ag–Pd interaction, which inhibits the release of Ag ions from the surface. Ag, in combination with Pd has no toxic effects and demonstrates useful antimicrobial properties. The Ti(94)Ag(3)Pd(3) alloy shows a good potential to be applied as a biomedical implant alloy.
