Great demands exist for more efficient in artificial bone implant design to replace or repair existing fracture or damage bone. Alloys are the established materials that have been used and studied in surgical implant application due to it durability and low wear resistance. Conventional method in fabrication of implant application normally adopted casting technique. However, this technique has limitation due to high melting point to achieve. Alternatively, implant alloys fabricated by using powder metallurgy technique. Besides, this technique also can control porosity and provide better mechanical properties. In this paper, the fabrication process of cobalt implant composite (CIC) using powder metallurgy technique is described and the material properties of CIC are identified. From the observation, increasing weight percent of hydroxyapatite (HAP) will affect the hardness and density properties of the cobalt implant composite, which will decrease the hardness value and same result for the density measurement and compressive strength of the CIC.
