| Abstract Scope |
Incorporating reinforced particles into lightweight materials like aluminum to produce mechanically strong metal matrix composites (MMCs) is a promising approach for automotive components such as pistons, brake rotors, and connecting rods. However, the fabrication of MMCs using fusion-based additive manufacturing poses challenges, specifically in second, sixth, and seventh-series aluminum alloys. Fabricating MMCs by utilizing the solid-deposition principle of friction stir surfacing-based additive manufacturing (FSSAM) can be a potential solution. In this work, FSSAM was performed to produce AA6063/SiC composite with a customized mechtrode fabricated from a tube and solid rod featuring a narrow clearance filled with SiC powder, followed by additional friction stir processing (FSP). The FSP facilitated a smooth deposited layer with uniform intermixing of SiC particles in the Al matrix. The wear test results showed significant wear resistance of MMC over base Al. Moreover, the interlayer diffusion showed good mechanical bonding between the substrate and the deposited layer. |
