Abstract: Composite materials are potentially attractive for a wide range of medical and mechanical applications. In the present investigation Hydroxyapatite (HA) compositehave been successfully prepared by a sol-gel auto combustion and sol-gel method respectively. This prepared
material was characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM),Energy Dispersive Spectroscopy (EDS) and Transmission Electron Microscopy (TEM).Friction and wear characteristics of HA composite were determined using a pin-on-disc tribometer at applied loads of 50-110 N. Result show that the wear performance of HA was superior and obtaining lower friction coefficients than the WM. To calculate the wear depth by Archard wear
model FEA is done. It has observed that no significant difference in between experimental and numerical wear depth.
