알루미늄 기반 나노 표면의 내부식 특성 연구

Abstract

Aluminum is a popular material for various energy and environmental applications including heat exchangers, pipes, space crafts and plant modules. We investigated surface modification techniques for aluminum surfaces in order to control both the morphological and chemical characteristics of aluminum surfaces. The effects of such modifications on the surface properties were investigated by FE-SEM, EDS and dynamic contact angles were characterized by high-precision goniometer. The corrosion resistance was characterized by measuring the corrosion potential and breakdown potential. Using the anodic scan measurements, we quantified the effects of surface oxidation itself and air-gap induced by inducing super hydrophobicity on corrosion resistance separately to help develop scalable aluminum nano-surfaces with high corrosion resistance.h the morphological and chemical characteristics of aluminum surfaces.
