针对船体结构钢16 Mn处于海水腐蚀与交变载荷的交互作用,并且在阴极保护作用下工作的实际工况,研究了阴极保护对16 Mn船体结构钢在海水和3.5%NaCl水溶液中的腐蚀疲劳裂纹萌生和裂纹扩展的行为。结果表明裂纹扩展速率不仅受阴极电位的影响而且受环境介质的影响。
Aiming at the interaction between seawater corrosion and alternating load of 16 Mn hull structural steel and the working conditions under cathodic protection, the corrosion fatigue of 16 Mn hull structural steel in seawater and 3.5% NaCl aqueous solution was studied. Crack initiation and crack propagation behavior. The results show that the crack propagation rate is affected not only by the cathode potential but also by the environmental medium.
