| Research Abstract |
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.
