The possibility of obtaining. Composite al18wt%si/sic by compocasting process
Abstract
The aim of this study was to investigate the influence of various process parameters on the microstructure of composite materials based on alloys All 8Wt%Si with the addition of 10Wt%SiC. The effect of stirring speed (1000 and 1500 rpm), stirring time 15 min and casting temperature 565 degrees C on the structural and mechanical properties are discussed. It was found that applying the stirring speed of 1500 rpm in semisolid state the best distribution of SiC particles in the matrix was achieved, which gave satisfying mechanical properties. In order to evaluate the quality of obtained composites and their possible application in the practice, tests were carried out under conditions of cavitation. Cavitation damage to the composite samples was determined using modified vibratory cavitation equipment. Mass loss and surface analysis of composite samples during the experiment were used as an indicator the level of cavitation damage. The results showed very good cavitation resistance which gi...ves the possibility of using these materials in condition where cavitation resistance is needed.
