【 摘 要 】

In this contemporary work, particulates of coconut shell ash and boron carbide were reinforced with an atomized aluminium powder hybrid composites was prepared by the powder metallurgy process. The process parameters in powder metallurgy influence the various material properties. Compaction pressure, sintering temperature and weight percentage of coconut shell ash were selected as influencing parameters. An empirical relationship has been formulated using response surface methodology. The properties such as hardness, relative density and percentage of porosity are considered a response. Variance of analysis was employed to determine the significance of process parameters on the responses and to determine the optimal combination of parameters. High harness value of 165.1 HV, maximum density of 0.819 g/cc and minimal porosity of 8.15 % was obtained for the optimum condition.
