| Summary: | Friction stir processing is a novel process evolved to fabricate surface metal matrix
composites. Rice husk ash (RHA) is an agro-industrial waste and by product of rice husk. The
feasibility of incorporating RHA powder into aluminium alloy AA6061-0 as reinforcement particles
to make surface matrix composite via FSP is reported in this paper. The optical micrographs
revealed a homogeneous distribution of RHA particles which were well bonded with the matrix in
both first and fourth-passes of the FSP due to mechanical stirring. Microhardness of the stir zone SZ
with the RHA particles of I-pass increased to about 106 HV, 40% higher than that of the base
material 66 HV by dispersed RHA particles. |
