dc.description.abstractThe aim of this work was to test the influence of various process parameters to obtain composite materials based on the Al18Wt%Si alloy with addition of 10Wt%SiC.For a comparative analysis purposes, the samples obtained by rheocasting process were being casted with application of the rotation speed of 1500rpm, temperature of 565 degrees C and the time of 15 minutes.Having applied a combined stirring procedure from 500 - 1500rpm, it was noticed in the semisolid state that the best paricle distribution of the reinforcing material (SiC) was attained in the.metal matrix composite. The total time required for a compocasting process was 15 minutes; the samples were being casted from the temperature of 565 degrees C. cavitation damage of both composite samples and the samples obtained by rheocasting process was being determined with application of a modified vibration-cavitation equipment. A mass loss and an analysis of the sample surface during the experiment were used as an indicator to determine the level of sample damage caused by cavitation. Test results show a very good resistance to cavitation of composite materials, facilitating a possibility to apply these materials in the conditions demanding cavitation resistance. In the case of rheocasting samples, cavitation resistance is conditioned by presence of porosity leading to faster wear.en
