Paper Abstract

A UV pulsed lasers was employed to produce C and Ti ions of different charge with current densities of the order of 10 mA/cm2. A post ion acceleration, up to 30 kV, was employed to increase the ion energy and to implant polyethylene biocompatible surfaces up to a depth of about 200 nm. Preliminary results about surface properties indicate that implanted surfaces have higher wetting and micro-hardness with respect to un-implanted ones.
