Abstract
Komposit merupakan salah satu material yang terus dikembangkan, karena sifatnya yang kuat dan ringan. Proses pembuatan material dengan metoda metalurgi serbuk memiliki berbagai kelebihan diantaranya material komposit tercampur secara homogen. Pada penelitian ini dilakukan sintesis dan karakterisasi material komposit Al-Cu-Mg dengan variasi filler SiC, komposisi Cu yang digunakan sebanyak 4,4 wt%. Mg sebanyak 1,8 wt% dan variasi SiC yaitu 4,5 wt%, 5 wt%, dan 5,5 wt%. Serbuk Al, Cu, Mg, dan SiC di-mixing selama 30 menit, lalu dijadikan bentuk pelet dengan kompaksi menggunakan tekanan 6 ton pada suhu 325 ̊c heat treatment yang diberikan berupa sintering, annealing, dan aging. Hasil XRD menunjukan terbentuknya fasa baru yaitu fasa Al2Cu, dan fasa Al2CuMg dan hasil korosi menunjukan peningkatan nilai laju korosi sebanding dengan peningkatan komposisi SiC. Composite is one of the materials that are constantly developed, because of its strong and lightweight. The process of making the material by powder metallurgy method has various advantages such as composite material mixed homogeneously. In this research, synthesis and characterization of Al-Cu-Mg composite material with SiC filler variation, Cu composition used was 4.4 wt%. Mg as much as 1.8 wt% and SiC variations are 4.5 wt%, 5 wt%, and 5.5 wt%. The powder of Al, Cu, Mg, and SiC mixed for 30 minutes, then used as pellet form with compaction using pressure of 6 tons at 325 ̊c. Heat treatment given in the form of sintering, annealing, and aging. The XRD results show the formation of new phase are Al2Cu phase, and Al2CuMg phase and corrosion result show an increase of corrosion rate value proportional to increasing SiC composition.
