ANALISIS LAJU KOROSI KEKERASAN DAN MIKROSTRUKTUR PADA AMC 3%PKSA DAN 1%SIC YANG DIFABRIKASI DENGAN METODE STIR-SQUEEZE CASTING

Palm kernel shell ash (PKSA) is an abundant biomass material that can be utilized as a reinforcement for aluminum composites due to its low cost, environmental friendliness, and ability to enhance mechanical properties. This study develops an Aluminum Matrix Composite (AMC) based on Aluminium 6063 reinforced with 3% PKSA and 1% SiC to improve its strength and corrosion resistance. The composites were fabricated using the Stir–Squeeze Casting method with applied loads of 3 tons, 6 tons, and 9 tons. The results show that increasing the squeeze load produces a denser and more homogeneous microstructure with minimal porosity. Corrosion testing conducted according to ASTM G31-72 in 1 M H₂SO₄ revealed that the highest corrosion rate occurred in the 3-ton sample (±1262 mpy), followed by 6 tons (±580 mpy), while the 9-ton sample had the lowest rate (±492 mpy). Brinell hardness tests indicated that the 6-ton sample achieved the highest values (50–53 BHN), whereas the 9-ton sample ranged between 45–52 BHN. Microstructural observations supported these findings, with the 9-ton sample showing the most uniform particle distribution and minimal porosity. All samples experienced pitting corrosion after immersion, with the most severe damage observed in the 3-ton sample. Overall, the addition of PKSA and SiC successfully enhanced the mechanical properties and corrosion resistance of Aluminium 6063. The squeeze load significantly influenced the composite quality, where 9 tons provided the best corrosion resistance and 6 tons yielded the highest hardness.
