Conclusion
Because more materials with better wear characteristics need to be found, some possible areas that deserve more attention are the ion implantation of metals, ceramic materials, or new polymer materials. Some recent research includes developing diamond-like coatings to carbon-carbon composites with an aim of making the material a life-long implant and coatings for titanium implants in order to encourage bone growth. Currently, to anchor a titanium implant in place, the metal is coated with hydroxyapatite, a mineral that makes up 75 percent of bone, but often the implant loosens, causing failure of the implant. The research that needs to be done should involve materials that are as flexible as bone and that are compatible with the body.
