利用自制的海洋环境金属材料腐蚀模拟试验机,用失重法研究了分别挂片方式和电连接挂片方式的地钢在海洋环境的大气区、飞溅区、潮差区和全浸区中的腐蚀行为。研究结果表明,无论是分别挂片还是电连接挂片,A_3钢在海洋环境的不同区域的腐蚀速度存在着差异,同时,电连接挂片和分别挂片在各个区域的腐蚀规律有着明显的不同。并且对产生这些现象的原因进行讨论。
Using the self-made corrosion test machine for marine environment metal materials, the corrosion resistance of the ground steel in the atmospheric, splashing, tidal range and immersion zone of the marine environment was studied by the method of weight loss. behavior. The results show that there is a difference in the corrosion rate of A 3 steel in different regions of the marine environment, whether it is the separate coupons or the electrically connected coupons. At the same time, the corrosion patterns of the electrical coupons and the coupons in each area are obviously different . And the reasons for these phenomena are discussed.
