Abstract

Nitrogen and argon ions were irradiated on the surface of aluminum alloy. Ion irradiation appeared to increase contact angle of the metallic specimens. In order to investigate the factors affecting the changes of contact angles, changes in the characteristics of the surfaces were examined using SEM, AFM, and X-ray diffraction. The contact angle increased due to surface composition changes and surface roughness changes.
