Abstract
It is well establishes now that alloying elements play an important part in controlling the behaviour of dental amalgam. The primary constituents are Ag, Sn, Cu, and sometimes Zn which were traditionally carefully chosen for certain specific characteristics. In this work, however, (0.5-1) % ZnO and TiO2 were added separately and together to the control sample (low copper). Tafel extrapolation technique was used to investigate the corrosion behavior, while (Pin-on-Disc) wear test was also conducted. The corrosion current density of hybrid sample was only 41% of the corresponding value of the control. While the weight loss in the wear test of the same sample was 14% of the corresponding value of the control sample.
