Abstract
Blood cockle shell (Anadara granosa) waste has potential as reinforcement in metal matrix composites due to its calcium oxide (CaO) and magnesium oxide (MgO) content. This study aims to analyze the effect of Anadara granosa powder volume fraction on the erosion resistance, hardness, and microstructure of Al 6061 composites. The specimens were fabricated using Al 6061 as the matrix with reinforcement variations of 0%, 5%, 10%, and 15% through casting and standard material preparation. Erosion resistance was tested using the sand blasting method at a 30° impact angle and 0.49 MPa nozzle pressure with silica sand (SiO₂) as the erodent. Hardness was measured by the Vickers method, while microstructure was observed using a Scanning Electron Microscope (SEM). The results show that the variation of reinforcement significantly influences the mechanical properties and erosion resistance. The addition of 10% Anadara granosa powder produced the highest hardness and erosion resistance compared to other specimens. However, at 15%, performance decreased due to particle agglomeration, voids, and non-uniform distribution. SEM analysis confirmed better matrix–reinforcement bonding at 5% and 10%, while porosity and particle pull-out were evident at 15%. In conclusion, the optimal reinforcement fraction of Anadara granosa powder in Al 6061 composites is 10%, which provides the best balance of mechanical properties, erosion resistance, and microstructural stability. Keywords: Al 6061, Anadara granosa, composite, erosion, hardness.
