Abstract
Aluminum-based alloy composites with high strength and low density can be used in corrosive environments. In this research, the nano-powders of A16061 alloy and A16061/TiB2 composite were synthesized by mechanical alloying (MA) method. Then, A16061 /TiB2 nano-composite bulk samples were prepared at laboratory scale by hot extrusion approach. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) devices were respectively used for measurement of particles and grains, and the polarization test was employed to assess the corrosion behavior of A16061/TiB2 nano-composites. The grains size of hot extrusion samples were calculated as about 95 nm. Uniform corrosion behavior and pitting of the produced nano samples of MA6061 /1.25 TiB2 have higher corrosion resistance compared to the alloy samples of MA6061.
