Reinforcing pure titanium with 12 percent molybdenum and various weight percentages of zirconia increased the microstructure, mechanical properties, corrosion behaviour, and biocompatibility. To obtain a homogeneous distribution of Mo and ZrO2 in the titanium matrix, powder metallurgy is used. For the manufacture of composite powders, mechanical milling with a ball mill machine was employed, with a 10:1 ball to powder ratio, 100 rpm for a 24 hour milling time, and alumina ceramic balls of 10 mm diameter in an argon atmosphere. 2 wt ethanol is used as a process control agent. Powders of Ti–12Mo/(x)ZrO2 composites are cold compacted in a die with dimensions of 17 x 12 mm2 by a uniaxial press under 600 MPa. To select the best suitable temperature, the compacted samples are sintered at three different temperatures: 1350C, 1450C, and 1500C for 90 minutes. The microstructure of the manufactured Ti–12Mo/ZrO2 composites, as well as parameters such as density hardness, wear rates, corrosion resistance, and biocompatibility, were investigated. The density of pure Ti was raised by adding 12 wt. percent Mo and increasing the ZrO2 percentage to 5 wt. percent, according to the findings. The eutectoid phase was created by adding 12 wt.% Mo to the titanium matrix to reinforce it. The 5 wt. percent ZrO2 sample had the maximum hardness and the lowest wear rate. In the simulated saliva fluid, the Ti–12Mo/(x)ZrO2 composites demonstrate excellent corrosion resistance (SSF). Both Ti, Mo, and Zr ions produced in SSF from Ti–12Mo/(x)ZrO2 nanocomposites were found to be exceedingly low. The findings showed that Ti–12Mo/5 wt. percent ZrO2 composites have a lot of potential for dental implant applications. The biocompatibility test was estimated for all samples. The data also demonstrated that the 5 wt. percent ZrO2 sample achieves high adherence and proliferation of living cells.
