In this research, spark plasma sintering (SPS) was used as a new method in the fabrication of Al–Al2O3 composites. Theeffect of Al2O3particle size (both nano and micron) and its amount on the relative density, hardness, resistance, corrosionand compressive strength in Al–Al2O3 composite were investigated. Evaluation and size characterization of nano particlewas carried out by transmission electron microscope. The distribution of particles throughout sample, as well as the detectionof the elements in the structure were studied by scanning electron microscopy equipped by corresponding energy dispersiveX-ray spectrometer analysis. According to the results, in the sample containing 3 wt% of nanoparticle of Al2O3,the mechanicalproperties of composite and corrosion resistance were improved due to uniform distribution of Al2O3nanoparticles. However, by increasing weight percent or particle size of Al2O3in composite, properties such as corrosion resistance andmechanical strength were considerably reduced. It can be attributed to the porosity and agglomeration of particle that wereproduced in composite.
