Özet

In this study, pure titanium particle samples with different particle sizes were produced by powder metallurgy method. In the sample production, pure titanium particles having a different particle size of <= 30 mu m, <= 43 mu m, <= 150 mu m were used. Titanium (Ti) samples were sintered at 1100 degrees C for 120 min. Density, hardness, wear resistance and microstructure analyzes were performed on the Titanium samples. According to the results, the best mechanical properties values were obtained with <= 30 mu m particle size of Titanium. The best density and hardness results are 4.28 g.cm(-3) and 419.8 HV, respectively. The results of the wear rate were found under 30 N load of 8.21 x 10(-5) mm(-3).Nm. Mass loss results were measured as 5.2 mg (under load of 30 N). SEM analyses showed that a good bonding and strong neck formation between the particles were observed for particle size of <= 30 mu m.
