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.
进行了髋关节模拟器研究，以调查由氧化铝陶瓷制成的股骨头与钛杯中碳纤维增强塑料（CFRP）镶嵌物之间的初始磨损情况。施加了2500 N的载荷和0.857 Hz的频率。在200,000次循环后，股骨头中心向衬里移动了9微米。在500,000次循环后，杯中心又向内移动了1微米，近半径增加了2微米。在750,000次循环后，股骨头中心的位置保持不变，而平均半径又增加了2微米。在一百万次循环后，任何进一步的变化都保持在系统测量能力（1微米）以下。
