High density polyethylene (PE) was modified by argon plasma discharge and then coated with 50 nm thick gold layer. Surface morphology of as-modified PE samples and samples coated with Au was studied using atomic force microscopy technique. The surface polarity was characterized by contact angles measured by standard goniometry. A nanoindenter was used to examine the sample's mechanical properties (hardness, elasticity modulus, scratch behavior). The Au layers were characterized using X-ray diffraction. The plasma modification of PE leads to a strong decrease of the water contact angle, which further depends on the time elapsed after the plasma treatment. Because of plasma-initiated ablation, a lamellar arrangement of PE polymeric chains becomes apparent on the plasma-treated samples.
