Microstructural evolution, electrical conductivity, and electrochemical analysis of α-Al-CNTs-GAg.NPs high-conductor nanocomposite

A new composites material was developed to decrease the chloride attack on aluminum high conductivity using carbon nanotubes (CNTs) and green synthesis silver nanoparticles (GAgNPs) via spark plasma sintering method (SPS). The microstructures, X-diffraction, the electrical conductivity of the composites were determined. Al-CNTs+2%GAgNPs composite was successfully produced using high intensive balling and sparks plasma sintering. A 91.08 and 95;56% protection efficiency were obtained over that of the α–Al Matrix at Al-4%CNTs and Al-4%CNTs+2%GAgNPs. The additions of 4%CNTs and 2%GAg.NPs have been able to reduce the Cl⁻¹ ion attack on α–Al Matrix. A 7.8% and 93.11% raises in the electrical conductivity at Al-4%CNTs and Al-4%CNTs+2%GAgNPs composites. It was established that addition of 2%GAgNPs to Al-4%CNTs can be used in the production of high conductivity materials with better corrosion protection.
