Hip Fretting Corrosion Test

 

Fretting corrosion test for the femoral head-neck taper connection. Method 1: determines damage through assessing corrosion products and particulate debris after 10 million cycles of axial load applied to the femoral head in a saline fluid environment to simulate mechanically assisted crevice corrosion. Method II: is a shorter-term electrochemical evaluation of fretting corrosion examining change in voltage potential between anodic and cathodic components of the THR.
