Abstract

In the presented work two methods of casting: gravity casting and centrifugal casting have been described. The main aim of the study was development procedures for producing the AlSi/SiC+C hybrid composite. Selection of reinforced particles was made on their tribological characteristics. SiC particles in the matrix alloy for its high abrasion resistance and hardness, glassy carbon particles for obtaining a low coefficient of friction. Composite suspensions with the same phase composition were cast into molds with different coefficients of thermal conductivity. This allowed to determine the influence of thermal conditions on the formation of the structure and distribution of particles in the matrix. The structure of cast composites was examined by light and electron microscope, applying properly made preparations. In the paper the conditions of casting, macro-and microstructure and selected properties of the casts have been presented.
