| Summary: | In this study, the tribological performance of Al6061-SiCp
composite is investigated considering the influence of stir
casting process parameters. The wear and frictional
characteristics were studied using the dry reciprocating
wear testing machine. Experimentation is generated through
the central composite design (CCD) using a four factor five
level design plan. The process parameters (reinforcement
fraction wt%, stirring speed rpm, processing temperature °C
and processing time s) are examined using ANOVA and
multiple objective optimization (MOO) analysis. The result
shows that stirring speed has the most significant
contribution in controlling the wear and friction
characteristics. Confirmation test is also conducted to verify
and validate the process parameters in order to optimize the
tribological output. Moreover, characterization of the
composite wear scar mechanism is performed using
scanning electron microscope. This study provides an
effective method of minimizing the tribological properties
of Al6061-SiCp composite by optimizing the stir casting
process parameters. |
