Effect of pure titanium particle size on density, hardness, wear resistance and microstructure properties
Keywords:Titanium, Particle size, Hardness, Wear resistance, Microstructure
AbstractIn 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 â‰¤30Âµm, â‰¤43Âµm, â‰¤150Âµm were used. Titanium (Ti) samples were sintered at 1100Â°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 â‰¤30 Âµm particle size of Titanium. The best density and hardness results are 4.28 gÂ·cm-3 and 419.8 HV, respectively. The results of the wear rate were found under 30 N load of 8.21Ã—10-5 mm3Â·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 â‰¤30 Âµm.
