Wear Resistance of Nano-ZrO2 ceramic for Hip Joint Head Prostheses
By using the ring-block friction and wear machine,the friction and wear behavior ofnano-ZrO2 ceramic test block against GCr1 5 steel test ring has been studied.At the same time,friction and wear test of 45# steel block against GCr 15 steel ring has also been conducted for comparison.By using self-made test machine for the wear ability of the hip joint,the friction test of nano-ZrO2 ceramic hip joint head against ultra-high molecular weight polyethylene (UHMWPE) acetabulum has been done,the friction test of Co-Cr-Mo alloy hip joint head against UHMWPE acetabulum has also been made for comparison.The results show that the friction factor of nano-ZrO2 ceramic test block against GCr15 steel test ring is less 37.3% than that of 45# steel block against GCr15 steel ring,the wear weight of nano-ZrO2 ceramic test block against GCr15 steel test ring is only 0.76% of that of 45# steel block against GCr15 steel ring.The wear weight of UHMWPE acetabulum against nano-ZrO2 ceramic hip joint head is 61.5% of UHMWPE acetabulum against Co-Cr-Mo alloy hip joint head.This indicates nano-ZrO2 ceramic has good wear resistance property and is the ideal materials for artificial Hip joint head Prostheses.
