title: [Wear behavior of coupled aluminum oxide ceramics-carbon fiber bond as hip acetabulum inlay in a simulated trial].
abstract: Hip-simulator studies were carried out to investigate the initial wear between a femoral head made of aluminium oxide ceramic and a CFRP-(carbon fibre-reinforced plastic) inlay in a titanium cup. A load of 2500 N and a frequency of 0.857 Hz were applied. After 200,000 cycles, the centre of the head had moved 9 microns into the liner. After 500,000 cycles, the cup centre had moved inwards by a further micron, and the near radius had increased by 2 microns. After 750,000 cycles the position of the centre of the head remained unchanged, while the mean radius had increased a further 2 microns. After one million cycles any further changes remained below the measuring capability (1 micron) of the system.
