Abstract

In this research, all the samples are prepared using the powder metallurgy technique by adding silver element and Zirconia ceramic material to the commercially pure titanium at a different weight percent of (10, 20 and 30) to investigate the effect of adding these materials to the CP-Ti on corrosion behavior and mechanical properties. There are two sets of each type of alloys Ti-Ag and Ti ZrO2. The Preparation process was by Weighing, Mixing and Homogenizing Powders by Ball Mill, compacting at 4 tons for 1 min. and Sintering at 700 and 900 °C for 2 hrs. under a controlled atmosphere. The corrosion results showed a good corrosion resistance increases with increasing the silver content as the corrosion rate would be the best in (30% Ag) content with(0.091 mpy) at sintering temperature of 700 °C. And with a sintering temperature of 900 °C, the best result was with (30% Ag) with (0.059) mpy. In the Ti-ZrO2 alloys, the best result was with the zirconia content of (30%ZrO2) when cooled in the air with (1.347) mpy at sintering temperature of 700 °C, this results obtained in Ringer’s solution. And microstructures analysis stated that at the silver and the Zirconia content of (10-20 wt%) single phase of  (α- Ti alloy), as the silver and Zirconia content increased to (30% wt), in addition to (α-phase), (Ti2Ag) intermetallic compound developed in the silver alloy microstructure and (TiZr)3O intermetallic compound developed in the microstructure of Ti- Zirconia composites and the hardness test result best hardness of...
