Abstract

Bioceramics are potentially attractive for a wide range of medical and mechanical applications. In the present investigation Hydroxyapatite (HA) and Willemite (WM)were successfully prepared by sol-gel auto combustion and sol-gel methods respectively. The prepared materials were 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 and WM were determined using a pin-on-disc tribometer at applied loads in the range of 50N -110N. Results reveal that the wear performance of HA was superior to WM also possess lower friction coefficients than WM. To calculate the wear depth by Archard wear model FEA is done. It was observed that no significant difference between experimental and numerical wear depth.
