KARAKTERISTIK LAJU KOROSI PADA KOMPOSIT ALUMUNIUM 6063 DENGAN PENAMBAHAN 1% PKSA DAN 3 % SIC MENGGUNAKAN METODE STIR-SQUEEZE CASTING

Indonesia, as the world’s largest producer of palm oil, generates a considerable amount of palm kernel shell (PKS) waste that remains underutilized. Palm kernel shell ash (PKSA), rich in silica and carbon, has the potential to serve as an economical, environmentally friendly, and easily available reinforcement material for Aluminium Matrix Composites (AMC) derived from industrial waste. This study aims to examine the influence of adding 1% PKSA and 3% silicon carbide (SiC) on the corrosion rate, hardness, and microstructure of Aluminium 6063 using the stir-squeeze casting method with pressure variations of 3, 6, and 9 tons. The experimental procedures included immersion corrosion testing in a 0.5 M H₂SO₄ solution for 48 and 144 hours, Brinell hardness testing, and microstructural analysis to observe particle distribution and bonding uniformity within the aluminium matrix. The results indicated that increasing squeeze pressure significantly enhanced the composite’s overall performance. At 3 tons, the corrosion rate was 0.0089 mpy with a hardness of 64.3 HB; at 6 tons, 0.0057 mpy with 72.4 HB; and at 9 tons, the lowest corrosion rate of 0.0034 mpy with the highest hardness of 79.6 HB was achieved. Microstructural observations revealed that higher pressure produced a denser, more homogeneous matrix with minimal porosity, signifying improved particle-matrix bonding. Therefore, the combination of 1% PKSA and 3% SiC through the high-pressure stir-squeeze casting process effectively enhances the hardness and corrosion resistance of Aluminium 6063 composites while promoting sustainable utilization of biomass waste for advanced material development.
