Haiyang gongcheng zhuangbei yu jishu, 2019 采用腐蚀浸泡和电化学方法研究了砂在腐蚀模拟介质中对X65管线钢的腐蚀行为影响，及缓蚀剂ZDE的缓蚀性能。实验结果表明，砂沉积使得X65钢在腐蚀模拟介质中的腐蚀速率增加，腐蚀加重。ZDE属于一种混合型缓蚀剂，在模拟盐溶液中对X65钢的腐蚀表现出了一定的阻碍作用。60°C，ZDE加注浓度为0.15 g/L时，无砂工况的缓蚀效率达83.52%；而试样表面砂覆盖后，缓蚀剂有效作用浓度下降，缓蚀效率降低。缓蚀剂ZDE加入后，其作用于碳钢表面，形成一层保护膜，使得金属/溶液界面处的电荷转移电阻增加 ...

Gongye shui chuli, 2002 从单因素、多因素和复杂水系考察了炼厂外排污水回用于循环冷却水腐蚀的影响因素,结果表明,碳钢腐蚀的主要影响因素取决于离子特性、氧化膜的形成和溶解氧的扩散等综合协同作用,其中以离子特性的影响为最大 (如 :Cl-、Ca2+ 、CO32- 的腐蚀性较强 )。碳钢腐蚀反应又可由以上三种主要影响因素分为三个反应控制区,而当电导率在 0 .1～ 2 .0mS/cm范围时,其水质属于腐蚀危险高发区。从而也进一步说明水质的低电导率处理,其防腐效果并不理想,相反在高电导率情况下却表现出相对较好的低腐蚀性能。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.
