Question
Hot isostatic pressing is to be used to produce the femoral head components of hip implants made from a novel grade of
zirconia.
A series of manufacturing trials have demonstrated that the processing route results in post-sintered surface features 43-
107 μm (mean 74 µm) in size. In clinical use it is anticipated that the femoral heads will be loaded to maximum stress
level of 50% of its tensile strength once implanted.
What is the critical flaw size when in service and will the implant require polishing for it to withstand loading during
clinical use?
Where:
. You may assume a value of 1.4 for Y
The grade of zirconia has a Tensile strength of 980 MPa and a fracture toughness of 11 MPa.m 0.5
