【摘要】 <正> 关于金属在海水中的耐蚀性,国外已进行了大量的工作但是国产金属材料现有的耐蚀性资料尚不足,所以测试各种金属在海洋环境中的耐蚀性是非常需要和紧迫的。当铜和筒合金浸泡在海水中,会遭受到不同程度的腐蚀,溶解下来的铜离子对防止海洋生物的附着有一定的抑制效果但其耐蚀性则往往还不能满足使用上的要求。所以在铜合金中加入适当的其它元素增加其耐性,从根本上解决材料的腐蚀问题,是一个非常重要的途径。更多还原

【Abstract】 Corrosion rate and electrode potentials of twelve copper-alloys, twostainless steel and one carbon steel have been detrmined by electrochemicalmethod. The corrosion resistance of the stainless steel has been testedafter being jointly welded in different atmosphere in the marine condition.Some metal materials have been selected which are not only of highercorrosion resistance but also of more fouling resistance.更多还原
