The purpose of this work is the characteristic modification by ion implantation of ultra high molecular weight polyethylene, and a preliminary study of its surface. This biomedical material has been chosen for its excellent chemical and physical properties. An ultraviolet-pulsed laser of 248nm was employed to produce, by laser ablation, C and Ti ions of different charges with current densities of the order of 10mA/cm2. The ions were accelerated by the application of a positive high voltage, 30kV, on the target support to accelerate ions to implant the polyethylene surfaces up to a depth of about 200nm. Preliminary results about surface properties indicate that implanted surfaces have higher wettability and micro-hardness values with respect to unimplanted ones.
