【 摘 要 】

The Effectiveness of the erosion process mainly depends on different properties of the erodent as well as the process parameters. The process parameters such as the impingement angle, Eroded velocity and erodent size have the significant effect on the productivity of the erosion mechanism. To investigate properly on aluminium-based metal matrix composite the erodent chosen was micro Al2O3. A Taguchi based design of experiment was conducted and the effect of the response parameters such as the erosion rate and Signal to Noise ratio (S/N ratio) were studied. It was observed that erosive behaviour of the surface and the mechanisms of material removal mainly depend on the shape and size of the crater formed by the erodent particles which are subjected to variation in shape, velocity & impact angle. Therefore, SEM Analysis was done to find out the surface characteristics and also developed mathematical model for output responses was examined by Analysis of variance (ANOVA) to investigate the suitability of the model. Finally, the cause and effect analyses of various eroded surface characteristics were studied in detail to find out the optimal parameter settings.
