Abstract
The purpose of this study was to evaluate the long‐term wear performance of alumina matrix composite (AMC) heads against alumina matrix composite inserts and alumina matrix composite heads against alumina (Al) inserts with the use of a hip‐joint simulator incorporating severe swing phase joint microseparation. The wear of AMC on Al produced an average wear rate of 0.61 mm3/million cycles over the 5‐million‐cycle test duration. The wear of AMC on AMC produced an average wear rate of 0.16 mm3/million cycles over the 5‐million‐cycle test duration. Both the AMC on alumina and AMC on AMC produced significantly lower wear than previously tested HIPed alumina, where an average wear rate of 1.84 mm3/million cycles was reported over 5 million cycles. The wear mechanisms and wear debris of AMC on AMC and AMC on Al were similar to those observed in previous alumina retrieval studies with stripe wear caused by intragranular fracture and wear debris consisting of predominantly uniform 10–20‐nm‐sized particles and a few irregular particles up to 3 μm in size. © 2003 Wiley Periodicals, Inc.
