| Abstract | ||
| A new generation of Al-hybrid composite was successfully fabricated using the powder metallurgy technique after the electroless chemical deposition of both nano Ni and Cu on the surface of Y2O3-SiC mixture particles. Al metal matrix (AMM) was reinforced with nano-Ag/Ni or nano-Ag/Cu coated (SiC-Y2O3) particles with 2.5, 5, and 7.5 wt% content by a 50:50 ratio of SiC to Y2O3. The microstructure was examined by optical, SEM, EDX, and TEM. The XRD also was used for phase identification. A wettability test was established on the sintered samples. The wear behavior was conducted. Evaluation of the corrosion feature of the AMM reinforced with (SiC+Y2O3)/ either nano-Ag/Ni or nano-Ag/Cu was investigated in 3.5% NaCl. The inhibiting impact in 3.5% NaCl solution was studied by potentiodynamic polarization (PDP). The AMM reinforced with (SiC+Y2O3)/nano-Ag/Cu has a good mixed-type corrosion inhibitor. Also, the corrosion rate decreased by increasing either nano-Ag/Ni or nano-Ag/Cu. The protecting film was formed on the AMM reinforced by either nano-Ag/Ni or nano-Ag/Cu and confirmed by SEM and EDX. | ||
