| Abstract Scope |
Several Additive Manufacturing (AM) processes have been developed in order to fabricate Metal Matrix Composites (MMCs). Most of these processes use carbon fibers or carbon nanotubes to mix with metal powder in order to be used in an existing AM process. Commercial applications of the existing processes are very limited due to: 1) Difficulties of mixing and, 2) Dispersion and distribution of carbon particles in the metal. This paper introduces a novel AM method for fabrication of metal-carbon by Thermal Decomposition of sugar. In this method sugar/sucrose are printed on metal powder bed to fabricate green part. The green part undergoes bulk sintering. During bulk sintering the printed sucrose is decomposed to carbon particles to form MMC reinforced by carbon. In order to further study the process X-ray Difraction (XRD), Scanning Electron Microscopy (SEM), and Energy-Dispersive X-ray Spectroscopy (EDS) techniques were used to analyze the fabricated bronze-carbon samples. |
