dc.description.resumoThis study aimed at investigating the influence of the processing conditions on the mechanical properties of hot pressed compacts of a CoCrMo biomedical alloy. Several hot pressed CoCrMo compacts were processed in vacuum (102 mbar), at a pressure of 60 MPa with different temperatures (900 C, 1000 C and 1100 C) and different times (10 min, 30 min and 60 min). Compacts were examined by SEM/EDS. The transverse rupture strength, Young’s Moduli and hardness were determined. The fracture surface of compacts were also examined. The compacts hot pressed at 900 C exhibited lower TRS than those processed at 1000 C and 1100 C, which showed similar strength values, regardless the sintering time. The 900 C compacts showed also lower YM and higher porosity. Lower hardness values were registered for 900 C compacts while 1000 C compacts exhibited the highest values. The fracture surface analyses revealed fragile fracture for 900 C compacts (10 min and 30 min) and 1000 C (10 min). The remaining compacts exhibited ductile fracture. A full characterization of the mechanical properties of hot pressed CoCrMo compacts has been made and the selection of the processing parameters according to the desired mechanical properties is now possible.pt_BR
