Abstract

Ti-based alloys containing Ag were produced by tilt-casting method and their properties were studied. Even in its as-cast state, Ti₉₄Ag₃Pd₃ showed relatively high tensile properties, good electrochemical behavior, and good biocompatibility. The relatively good mechanical properties of the as-cast α-Ti-type Ti₉₄Ag₃Pd₃ 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 Ti₉₄Ag₃Pd₃ 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 Ti₉₄Ag₃Pd₃ alloy shows a good potential to be applied as a biomedical implant alloy.

The relatively good mechanical properties of the as-cast α-Ti-type Ti94Ag3Pd3 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 Ti94Ag3Pd3 can be explained by the Ag-Pd interaction, which inhibits the release of Ag ions from the surface.
