Abstract

In the present work Al4Cu-SiC composites were fabricated in a rigid die on a single-action compaction press and then sintered under the nitrogen atmosphere. The SiC (< 2 µm) content was 5 and 10 wt%. An attempt has been made to study the mechanical and tribological properties of fabricated materials. The microstructure of composite materials was analyzed with scanning electron microscopy (SEM) and X-ray diffraction (XRD). The obtained results indicated that introduction the ceramic particles into Al4Cu matrix resulted in an increase of most mechanical properties compared to the matrix material. However, the tribological properties were higher for unreinforced Al4Cu matrix than for composites with the addition of SiC.
