Abstract

This study investigated the methodologies to enhance the corrosion resistance and the ways to measure for subsea equipment made of aluminum. The methodologies for the anticorrosion were cathodic protection, conversion coating, anodizing and organic coating. The simply analyzed ways to measure the corrosion resistance were Scanning Electron Microscope (SEM), Electrochemical Impedance Spectroscopy (EIS), Glow discharge optical emission spectrum spectroscopy (GD-OES), Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS), Scanning Vibrating Electrode Technique (SVET), contact angle and interfacial tension. The most widely used tools for increasing the corrosion resistance were the anodizing and the organic coating. Many ways were evenly used to measure corrosion. The methods more frequently utilized were SEM for the surface investigation and the contact angle to evaluate the corrosion resistance.

본 연구에서는 알루미늄으로 제작된 심해 장비의 부식 저항 능력 향상시키기 위해 알루미늄 부식 방지 방법과 측정방법을 조사하였다. 조사된 부식 방지 방법은 Cathodic Protection(음극화 보호), Conversion Coating, Anodizing, 및 Organic Coating이었다. 그리고 간단하게 조사된 측정 방법은 Scanning Electron Microscope (SEM), Electrochemical Impedance Spectroscopy (EIS), Glow discharge optical emission spectrum spectroscopy (GD-OES), Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS), Scanning Vibrating Electrode Technique (SVET), Contact Angle(접촉각), Interfacial Tension (경계면 장력)이었다. 알루미늄 부식을 방지하기 위해 널리 사용되는 방법은 Anodizing과 Organic Coating이었으며, 부식 측정을 위해서는 여러 방법들이 골고루 사용되었다. 그 중 많이 사용되는 방법은 표면의 구조를 관찰하 위한 SEM과 부식 저항 능력을 측정하기 위한 접촉각 측정이었다.
