Abstract
In this work, Metal‐Gas Hybrid Ion Implantation technique was used as a tool for the surface modification of Ultra High Molecular Weight Polyethylene (UHMWPE). Samples were Ti+O ion implanted by using Metal‐Vapour Vacuum Arc (MEVVA) ion implanter to a fluence of 5×1016 ion/cm2 for each species and extraction voltage of 30 kV. Untreated and surface treated samples were investigated by Rutherford Back Scattering (RBS) Spectrometry, Attenuated Total Reflectance—Fourier Transform Infrared (ATR‐FTIR) Spectroscopy, Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). Results indicate that Ti+O ion implantation can be applied on UHMWPE surfaces successfully. ATR‐FTIR spectra indicate that the C‐H concentration on the surface decreased after Ti+O implantation. Thermal characterization with TGA and DSC shows that polymeric decomposition temperature is shifted after ion implantation.
