Elaboration of technology for manufacturing aluminum-based metal-matrix composite material strengthened with hollow ceramic microspheres for using thereof in underwater equipment

Abstract

This paper deals with the study of capabilities for strengthening an aluminum alloy with hollow ceramic microspheres. The results of the microstructural analysis and the investigation of strength properties for the aluminum-silicon alloying system are described herein. For comparison Experiments have been carried out for comparison both with classical microspheres and with chromium- and chromium-carbide-coated microspheres to increase the melt adhesion to a microsphere
