“…The flat samples were tested using a steel pin at a linear velocity of 1 m/s, normal load of 12 N and duration of 120 minutes. POM/CNT nanocomposites samples were placed on the rotating disc with a stationary stainless steel pin that has end probe point diameter about 200 µm [24]. Before conducting the test, the samples were first cleaned using ethanol and then with distilled water at test completion.…”

“…Great improvements in wear performance occur only when implantation produces a change in the dominant mode of wear. Formation of surface oxide layers during the wear process is often associated with these changes in wear behavior [88,89]. Besides increasing the wear resistance nitrogen implantation also enhances bone conductivity of titanium [90].…”

“…This color modification is probably due to two different processes involving both thermal effect and dehydrogenation [7]. Thermal effect occurs when highly energetic ions pass trough the UHMWPE surface and dissipate some of their energy as heat onto the treated surface.…”

Nitrogen Plasma Immersion Ion Implantation (PIII) has been used to modify the surface chemical structure of Ultra High Molecular Weight Polyethylene (UHMWPE). Grinding and polishing processes based on abrasive papers and alumina pastes have been evaluated with regard to their results on the improvement of polymer surface roughness, which has shown to be of crucial importance for hardness characterization. Raman spectroscopy, XPS, and Nanoindentation tests were used to characterize the modified surfaces. Experimental results has shown that UHMWPE surface mechanical properties such as hardness and elastic modulus can be improved by induced chain cross-linking between the macromolecules on the polymer surface caused by nitrogen PIII. The new material formed on the surface is Diamond Like Carbon (DLC). As a significant improvement in hardness was obtained by DLC synthesis on the treated surface, it is expected a dramatic improvement of abrasion resistance and overall durability of prostheses made with PIII treated UHMWPE.
