Abstract

The electrochemical properties and released ions of binary Au-1.6mass%Ti alloy were evaluated in 0.9% NaCl and 1% lactic acid solutions and compared with those of Au-Ag-Pd alloy and Type 4 gold alloy. Rest potential and anodic polarization curve of Au-1.6mass%Ti alloy were almost the same as those of pure gold regardless of thermal condition (softening, hardening, or as cast). Among the alloys in comparison, the anodic polarization curve of Au-1.6mass%Ti alloy showed that it had the least current density and best stability when subject to electrochemical oxidation. Though Au-1.6mass%Ti alloy did release a small amount of Ti ions in 1% lactic acid solution, the amount of released Ti ions was not more than 1/5 of the amount released by pure titanium under the same condition. In the same vein, the total amount of ions released from Au-1.6mass%Ti alloy was much lower than that of the precious alloys in both solutions.
