Ion implantation to reduce wear on polyethylene prosthetic devices. Rept. for Aug 89-Jan 91
Abstract
Researchers studied the use of ion implantation to improve the wear performance of ultra high molecular weight polyethylene (UHMWPE). UHMWPE samples were implanted with high energy ions, tested for wear performance, and compared to unimplanted control samples. Surface friction and hardness measurements, Raman scattering, Rutherford backscattering (RBS), water contact angle, and film transfer tests were performed to characterize the surface property changes of implanted UHMWPE samples. Results indicated a 90% reduction in wear on implanted UHMWPE disks. Implantation increased surface microhardness and surface energy. The Raman spectrum revealed a diamond-like signature, indicting carbon bonds of a different nature than those found in unimplanted polyehtylene. Photographic analysis of pins used in wear testing revealed differences between implanted and unimplanted samples in the polyethylene film transferred in the initial stages of wear from the disk to the pin.
