Treatment Techniques on Aluminum to Modify the Surface Wetting Properties

Abstract

Dierent techniques of surface treatment are employed to modify the physical properties of aluminum surfaces. Experimental data report measurements of water wetting ability in aluminum surfaces treated with six dierent techniques: polishing, sanding, acid attach, laser ablation, ion implantation and nanoparticle deposition. Surfaces can be modied as a function of the dierent treatment parameters. Treatment duration, roughness and morphology play an important role in determining the properties from hydrophobic to hydrophilic behavior.
