초록
본 연구는 알루미늄 선체에 적용 가능한 표면처리기술을 확보하기 위해 알루미늄 합금, 방오도료, 우루시올 그리고 양극산화 후 비등수 실링처리된 시편에 대하여 천연해수에서 침적실험 및 유속실험을 실시하여 해양생물 부착 특성을 분석하였다. 침적실험 결과 방오도료를 제외한 모든 시편에서 해양생물이 번식하였으며, 알루미늄 합금과 우루시올시편은 부식손상이 동반되었다. 한편 부착된 해양생물은 유속실험에 의해 효과적으로 제거되었다.
Abstract
This study was conducted to investigate the growth characteristics of marine organisms on aluminum alloy, antifouling paint, urushiol, and anodizing specimens sealed in boiling water under the conditions of a marine immersion test. Thereafter, flow rate tests were carried out in natural seawater. The immersion tests revealed that the marine organisms reproduced on all specimens except the antifouling paint and that their reproduction on the aluminum alloy and urushiol specimens was accompanied by corrosion damage. Furthermore, the attached marine organisms were effectively removed during the flow rate test.
