Abstract

Powder metallurgy is a manufacturing process for a component that shape combine of making powder compaction. Determination final properties on hydroxyapatite (HAp)/Al2O3/SiC have an important role as a reinforced to determine the final properties on a biomaterial composite. Using of self-propagating high temperature synthesis (SHS) method can produces the material with high density, strength, ductility, and stiffness. Hybrid composites include the usage of ceramic and metal like aluminum, titanium, magnesium, copper, SiC, and Al2O3. By SHS method using the exothermic heat reaction in the solids between the powder that been compacted to produce many kinds of material on high temperature process. Sample on this research consists of HAp, Al, Ti, Mg, Cu, SiC, and Al2O3, it was mixed and compacted at 7 tons of pressure. Variable on this research consists of HAp, Al and Ti composition, and holding time on SHS process. SHS process carried out at 6000C for 2, 3, 4 hours. Highest hardness achieved on usage of composition 2 about 666,52 HVN with using of 20% HAp, 35% Al, 30% Ti and 3-hours of holding time. The lowest hardness about 400.78 HVN achieved on usage of composition 1 with using of 10% HAp, 40% Al, 35% Ti and 3-hours of holding time.
