Steel Pipe Internal Corrosion Protection Using Magnesium Anode: Impact of Protective Potential and Phase Layer Formation on Corrosion Rate

Figure 5

Time dependence of LPR corrosion rate in tap water depending on the test conditions: (a) the electrodes corrode in natural conditions; (b) the magnesium dissolution takes place in the setup (0.1 A applied current); (c) the magnesium dissolution takes place in the setup (0.1 A applied current) and the probe’s electrodes are connected as cathodes (cathodic protection).
