Mass Transfer Coefficient During Cathodic Protection of Low Carbon Steel in Seawater

The aim of this research is to calculate mass transfer coefficient, kd, during cathodic protection of low carbon steel in neutral seawater (3.5% W/V NaCl in distilled water with pH = 7). Two types of cathodic protection were used: First: Sacrificial anode cathodic protection (SACP) were a pipeli...

It was found that the kd increases with increasing temperature and volumetric flow rate of seawater, where kd ranged (0.24×10-6 – 41.6×10-6 m/s).
