The utility model relates to a medical carbon / CVD with gradient of pyrolytic carbon coating on the surface of carbon composite materials, including carbon / carbon composite material of carbon fiber, carbon / carbon composite carbon fiber material on the outer surface of a complex superimposed layer of carbon layer, the inner layer to the outer layer of carbon carbon multiple layer carbon layer thickness gradually reduced. Medical carbon / gradient CVD pyrolytic carbon coating the surface of the carbon composite material on the surface of carbon / carbon composites covered with multiple layers of pyrolytic carbon, can improve the wear resistance of medical carbon / carbon composite materials, prolong the service life of the carbon / carbon composites.
