The efficiency of Zero Charge Corrosion Protection on pure Mg by Planned Interval Test

The concept of zero charge potential (Epzc) is manipulated to eliminates the effect of the electric double layer in order to mitigate the corrosion reactions through the zero-charge corrosion protection (ZCCP) method. The efficiency of the ZCCP method was examined by planned intervals test on pure Mg metal in 3.5% NaCl solution. The test results showed that the tendency of both liquid corrosiveness and metal corrodibility are decreased from -1562.7mm/yr (Eocp) to -98.2mm/yr (Epzc). ZCCP technique was succeeded by corrosion protection efficiency of pure Mg which was recorded between 93 to 96% in 3.5%) NaCl solution.
