Daftar Isi:
- Aluminium growing 29 million tons per year, to 22 million tons of new aluminum and 7 million tons of aluminum scrap recycling. The use of recycled aluminum can rise economically and environmentally friendly. Aluminum in Indonesia needs to reach 200,000-300,000 tons per year for US $ 1,951.50 per ton. Though aluminum ore is a mineral that is a limited supply. When linked with the number of vehicles using the piston in Indonesia in 2011 reached 85,601,351 pieces. For replacement piston damage annually 3-4% and the average weight of the piston 3 ounces. If multiplied by the amount of the replaced piston reaches 16306.5 tons. 1 ton of aluminum at a price $ 1951.50, means the total amount of US $ 31,822,134 (Rp. 315 billion). The purpose of the research for the manufacture of prototype composite piston of the piston waste with the addition of silicon carbide (SiC) and magenesium using the steer casting and squeeze casting methode. The composition of the mixture with the code K1, K2, and K3. As a control piston 1000 Daihatsu Hijet. Pressure squeeze casting with a variation of 400, 600, and 800 MPa. The results of testing the chemical composition of the waste pistons for the content of Al and Si is still under the original chemical composition of the piston, so it needs the addition of material of silicon carbide (SiC) and Magnesium (Mg) to increase the mechanical strength. SEM microstructure testing appears to differences in the bond interface between matrix and reinforcement SiC. The composition of the mixture K3 at a pressure of 800 MPa has a bonding matrix and reinforcement interface is perfect. Aluminum matrix capable of wrap the surface of SiC. Microstructure results support the results of hardness. K3 mixture equal the piston Daihatsu Hijet-1000 by 76 HRB. it can be recommended for the manufacture of prototype composite piston Keyword: Aluminium, piston, composite, silicon carbide, squeeze casting
