摘要:

采用失重法和微观表征手段研究了海洋平台用D36钢母材及模拟焊缝在不同海洋环境下的初期腐蚀行为。结果表明，不同海洋环境下，D36钢母材和模拟焊缝初期腐蚀速率变化规律相同，均为飞溅>潮汐>海洋大气>全浸。相同条件下，焊缝腐蚀速率大于母材。D36钢母材在海洋大气和飞溅环境下呈现全面腐蚀伴随点蚀形貌，而在潮汐和全浸区呈均匀腐蚀形貌；焊缝在4种环境下均表现为全面腐蚀伴随点蚀。海洋大气环境下腐蚀产物中以不具有保护性的γ-FeOOH为主。飞溅区浪花冲刷作用导致锈层剥离，且氧浓度维持在饱和状态，导致腐蚀速率较高。潮汐区则是由于干湿循环导致腐蚀产物产生微裂纹，腐蚀产物不具有保护性。全浸区含氧量显著降低，阴极反应受抑制，腐蚀速率最低。D36钢中铁素体和珠光体在海洋环境下构成微电偶电池，其中铁素体为阳极被溶解。焊缝中珠光体比例增加，促进了局部腐蚀，使焊缝腐蚀速率大于母材。

Abstract：

The intense corrosiveness of marine environments has severely hindered the development of offshore oil and gas industry. In this paper, the initial corrosion behavior of D36 low carbon steel and its welds for offshore platforms in several simulated marine environments was investigated by weight loss measurements and microscopic characterization techniques. The results showed that the evolution of initial corrosion rates for both the base metal and welds of D36 steel were consistent, following the order: tidal zone > splash zone > marine atmosphere > full immersion zone; For the same test conditions, the corrosion rate of the welds exceeded that of the base metal. In the marine atmosphere and splash zones, the base metal exhibited a corrosion pattern of general corrosion accompanied by pitting corrosion, whereas it demonstrated uniform corrosion in the tidal and full immersion zones. The welds displayed general corrosion with pitting corrosion in all the four environments. In the marine atmosphere, corrosion products predominantly consisted of non-protective γ-FeOOH. In the splash zone, wave impacting led to rust layer detachment, maintaining oxygen saturation and resulting in a relatively high corrosion rate. In the tidal zone, wet-dry cycles induced micro-cracks in corrosion products, diminishing their protective performance. In the immersion zone, reduced oxygen content suppressed the cathodic reaction, leading to the lowest corrosion rate. On the D36 steel, micro-galvanic cells of ferrite with pearlite were emerged in the marine environment, where ferrite acted as the anode and underwent dissolution. Therefore, the increased proportion of pearlite in the welds could result in its local corrosion intensity, thereby the corrosion rate of the welds was higher than that of the base metal.
