This is Phase II of research solicited under the Small Business                 Research.                                                                                                                                                       Titanium based alloys are prime candidates for orthopedic implants due          to their excellent corrosion resistance, high fatigue strength, low             density, biocompatibility, and most importantly low modulus of                  elasticity.  However, the only undesirable feature of these alloys is           their poor wear resistance.                                                                                                                                     Results of experiments undertaken in Phase I study clearly shows that           the ion implantation process is an effective method for improving the           wear resistance of Titanium Alloy (Ti-6A1-4V) for prothesis.  The ion           implantation process substantially reduces the wear of the mating ultra         high-molecular weight polyetholene (UHMWPE) surface on which the                prosthesis articulates.                                                                                                                                         The objective of Phase II is:  to understand the fundamentals of the ion        beam interaction with titanium; to optimize implantation parameter for          maximum hardness; to investigate fatigue and corrosion improvement of           the ion implanted samples.                                                                                                                                      Johnson & Johnson Orthopedic Divisions in the process of entering into          an agreement with Spire Corporation to use ion implantation for surface         treatment of titanium devices.  This research can lead directly to a            process for commercialization.                                                                                                                                  The facilities of the organization are adequate to support the research.        An award for $179,599 in support of a two-year program is recommended.
