해양환경 중에서 Glass Flake 라이닝 강재의 부식과 캐비테이션 침식 방지에 관한 연구

다국어 초록 (Multilingual Abstract)

Port facilities and marine structures used in marine environment were encountered to corrosion damages because of the influence of CI-. Generally, to protect these accidents, mainly applied anti-corrosion paint and epoxy coating. But it was still remained erosion-corrosion damage such as impingement erosion, cavitation erosion, deposit attack. There was needs to develope the new coating materials to protective those corrosion damages.<br/>
This paper, polyester glass flake, vinylester glass flake lining and epoxy coating for SS400 were investigated electrochemical tests and cavitation erosion test for corrosion behaviour under sea water.<br/>
The main results obtained are as follows ;<br/>
1) Surface of epoxy coating appear erosion pin hole but surface of polyester glass flake and vinylester glass flake lining do not appear erosion pin hole after impingement-cavitation erosion test in sea water.<br/>
2) Weight loss of polyester glass flake and vinylester glass flake lining do not occur after impingement-cavitaton erosion test in sea water.<br/>
3) Corrosion current density of polyester glass flake lining less drained than epoxy coating and substrate under corrosion potential..<br/>
4) Corrosion current density of vinylester glass flake lining with three coating less drained than that of polyester glass flake lining with two coating.
