A Novel Method for Incorporation of Micron-Sized SiC Particles into Molten Pure Aluminum Utilizing a Co Coating

摘要: Ceramic particles typically do not have sufficiently high wettability by molten metal for effective bonding during matrix composite fabrication. In this study, a novel method has been used to overcome drawback. Micron-sized SiC were coated cobalt metallic layer using an electroless deposition method. A of on the was produced prior incorporation in pure aluminum order improve injected particle with matrix. For comparison, magnesium added melt separate experiments as wetting agent assess which more incorporation. It found that both these methods regard ceramic particulate compared samples as-received into SEM images indicated coating than fine (below 30 µm), while totally percentage higher sample Mg agent. addition, microhardness tests revealed leads fabrication harder due increased amount incorporation, ceramic-matrix bonding, and possibly also formation Al-Co intermetallic phases.
