Abstract
A new insight on the lubrication of artificial joint components is presented. Addition of small amounts of nanoscale diamond particles to an artificial joint promotes a substantial improvement in friction and wear behavior of the artificial joint surfaces. Artificial joint implants are made from a variety of materials ranging from metal alloys to polymers. Suitable methods of applying nanoscale diamond particles to an artificial joint include (i) coating an effective amount of nanoscale diamond particles onto the artificial joint prior to implants; (ii) applying a composition to the artificial joint during an artificial joint implanting surgery, wherein said composition comprises a biocompatible carrier fluid and an effective amount of nanoscale diamond particles dispersed in the biocompatible carrier fluid; (iii) injecting the composition for lubricating the artificial joint into the artificial joint.
