Hip Fretting Corrosion Test
This test evaluates the mechanical stability of the bore and cone interface of the head and stem junction of modular hip implants subject to cyclic loading. Two test methods for measuring fretting corrosion are included. Method I: determines damage through assessing fretting wear, corrosion products, and particulate debris after applying a minimum of 10 million cyclic load cycles to the taper junction in a saline or proteinaceous solution 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.
