At present, a well-designed hip joint has a lifetime of 10-15 years. Since this is rather short compared with an increasing lifetime of human, there is great need to improve the durability and clinical lifetime of artificial joints. Reduction of wear debris through the coating of the material surface is one of methods to improve the durability. Here we grow carbon nanotube(CNT) array and composite film(CNT terminated with graphite layers) on the artificial bone Co-Cr surfaces(Co-Cr). It is found that the carbon coating result in the reduction of friction coefficient by tribology experiment.

目前，设计良好的髋关节使用寿命为10-15年。由于与人类日益增长的寿命相比，这是相当短的，因此非常需要提高人工关节的耐用性和临床寿命。通过材料表面涂层减少磨损碎片是提高耐用性的方法之一。在这里，我们在人造骨钴铬表面（Co-Cr）上生长碳纳米管（CNT）阵列和复合膜（碳纳米管端接石墨层）。通过摩擦学实验发现碳涂层导致摩擦系数降低。
