| Abstract: | The influence of process parameters (atomization pressure, superheat temperature, flight distance, particle injection pressure and distance, fluidizing pressure ) on the shape of 2024/SiC_p preforms and their microstructure produced by spray co-deposition is described in this paper. More satisfactory shape-near disc with homongenous distribution of particulates and lower gas content preforms is obtained after a number of experiments. |
