Experimental Investigations on Microstructural and Dry Sliding Wear Behavior of Al-AlB2 Metal Matrix Composites

The present work deals with micro-structural and wears behavior of Al-AlB2 insitu composite. These composites containing 3 and 5wt% of insitu AlB2 particles were produced by exothermic dispersion (insitu) involving reaction between Al6061 and KBF4 halide salt. Micro-structural characterizations were...

Description
Summary:The present work deals with micro-structural and wears behavior of Al-AlB2 insitu composite. These composites containing 3 and 5wt% of insitu AlB2 particles were produced by exothermic dispersion (insitu) involving reaction between Al6061 and KBF4 halide salt. Micro-structural characterizations were conducted using SEM/EDX which revealed uniformly distributed AlB2 particulates in the Al6061 base matrix. The machine used to test and evaluate wear properties of the prepared composite specimens is pin on disc type, disc made up of EN32 steel was used as counter face and loads 29.43N, 39.24N and 49.05N and 100, 200 and 300 rpm were employed. The results revealed about wear details in terms of volumetric loss which is proportional to sliding speed and normal load applied for all the conditions
