Pengaruh Parameter Faktor Stir Casting pada Porositas KOmposit Al-SiC
Abstract: This research aims
to analyze the effect of stir casting factor parameters on Al-SiC composite porosity using Taguchi m: ethod. Composite materials used aluminum alloy Al-Si as matrix and SiC particle (silicon
carbide) sized -400 mesh as reinforcement.
Al-SiC composites specimen porosity was tested using Archimedes
principles. Experimental design
using L16 orthogonal
arrays Taguchi method standard.
Factors used for the experiment were SiC content, melt temperature, rotation speed and stirring time
duration, each using
4 variation. Experimental
results showed that
increasing SiC content parameters
and stirring rotation speed from 100 into 300 rpm can increase Al-SiC composite
oporosity, but increasing melt temperature
above 700 C and
stirring time from
10-30 minutes candecrease the
porosity. The most significant factor affecting Al-SiC composite porosity was
SiC conten with 84,7 % contribution. Microstructures of Al-SiC casting
composites were observed using scanning electron microscopy (SEM).
