Adaptive Corrosion Protection System Using Continuous Corrosion Measurement, Parameter Extraction, and Corrective Loop

Figure 8

The weight loss of the freely corroding and the protected metal samples for more than two weeks in (a) the sink water solution, (b) the 50 mg/L humic acid solution, (c) the wet soil bed, and (d) the dry sand bed. Two A36 steel samples, one freely corroding and the other protected, are tested in each corrosive medium. (a) The weight loss of the freely corroding and the protected samples in the sink water solution for 13 days. (b) The weight loss of the freely corroding and the protected samples in the 50 mg/L humic acid solution for 14 days. (c) The weight loss of the freely corroding and the protected samples in the wet soil bed for 14 days. (d) The weight loss of the freely corroding and the protected samples in the dry sand bed for 12 days. (e) The calculated average weight loss per day for the freely corroding and the protected samples in all corrosive mediums.
