The purpose of this fundamental engineering research is to modify               the surface of a polymer material, so that the material will have               a surface which is  significantly more wear resistant than                      present materials made from polymers.                                                                                                                           The surface will be altered by bombarding it with ions from                     different atoms such as: neon, titanium, aluminum, chlorine and                 fluorine.  The altered polymer materials will be tested for                     changes in surface hardness, coefficient of friction and wear                   resistance.  If this technique is successful a new generation of                polymer implants could ensue.
