- 摘要:
- 在海洋腐蚀模拟试验机中测定了A3钢分别挂片和电连接挂片处于大气区、飞溅区、潮差区和全浸区的腐蚀速度以及在介质不同运动状况（海浪）下试片的电偶电位、电偶电流、自腐蚀电位。试验结果与用宏腐蚀电池理论对电连接挂片和分别挂片在海洋环境中不同的腐蚀规律的阐释相吻合，为海洋环境中碳素结构钢的腐蚀与防护提供参考。
The corrosion rates of A3 steel have been measured in a corrosion simulator under sea water corrosion conditions by means of both hanging plate and electrical connected hanging plate methods in the air zone, splash zone, tidal range zone and all-submergence zone, and the couple potential, current and self-corrosion potential of the testing plates have also been tested in different mediums, tidal movement states. The experiments show that the testing results by both methods are correspond with the macro galvanic corrosion theory which could be applied in the corrosion prevention of carbon steel under seawater corrosion conditions.1996 ,4(4): 6-11 收稿日期：1996-4-16分类号：TG172参考文献：
