The dual mobility acetabular component includes an acetabular cup and a liner that engage one another in a relatively static relationship by way of a Morse taper. The acetabular cup and the liner may be manufactured from a metal material (e.g., titanium) that decreases the energy differential therebetween, to limit or eliminate the galvanic cell phenomenon that forms between adjacent surfaces thereof as a result of body fluid therein that remains captured in small gaps or spaces due to capillarity. As such, the dual mobility acetabular component may experience reduced fretting compared to conventional hip joints known in the art.
