ABSTRACT Cathodic protection prolongs the service life of fluid transport and offshore engineering components by suppressing corrosion. This study assesses the effect of two cathodic protection methods, such as impressed current cathodic protection (ICCP) and sacrificial anode cathodic protection (SACP), on three ferrous-based materials under laboratory-controlled corrosive wear conditions. The SACP was as effective as ICCP on the protection of the low alloy steel and white chromium cast iron under both solid and solid-free corrosive wear conditions. Under solid–liquid impingement, significant reductions in the material loss were also observed in both the direct impingement zone and the outer area (oblique angle of attack). This demonstrates the substantial impact of cathodic protection systems that are exposed to erosion–corrosion dominated environments.

腐蚀磨损条件下阴极保护方法对黑色金属工程材料的影响

摘要 阴极保护通过抑制腐蚀来延长流体输送和海洋工程部件的使用寿命。本研究评估了两种阴极保护方法，如外加电流阴极保护 (ICCP) 和牺牲阳极阴极保护 (SACP)，在实验室控制的腐蚀磨损条件下对三种铁基材料的影响。在固体和无固体腐蚀磨损条件下，SACP 在保护低合金钢和白铬铸铁方面与 ICCP 一样有效。在固-液冲击下，在直接冲击区和外部区域（斜攻角）也观察到材料损失显着减少。
