This study aims to compare the effect of Al2O3

nano-particle additions on the densification, mechanical and

electrochemical properties of Titanium (Ti) matrix composites.

The Ti and Al2O3 nano-particles were dry mixed and molded

using by traditional Powder Metallurgy (PM) techniques. After

the molded process, the samples were sintered at 1200ºC and

1300ºC for 60 min. under high level vacuum. Mechanical

property, microstructural characterization and electrochemical

property of the sintered samples were performed using tensile

testing, hardness, optical, scanning electron microscopy and

electrochemical corrosion experiments. All the powders,

fracture surfaces of sintered samples were examined using

scanning electron microscope. The sintered density of straight

as well as Al2O3 nano-particles reinforced Ti matrix composites

increases with the increase in sintering time. The additions of

Al2O3 nano-particles improve the hardness values and

corrosion behavior with the increase of sintering time.
