A study of the influence of magnetic water treatment on the calcium carbonate phase formation and the electrochemical corrosion behavior of carbon steel was carried out. The water was exposed to a magnetic field of 1 T with a speed of flow through the magnet of 0.77 m/s (1.56 ml/s). The observations demonstrated that the calcite is the main form of calcium carbonate, and became aragonite by action of the magnetic field. The aragonite content, expressed in wt.% with respect to the total calcium carbonate content, grew constantly with respect to the water without magnetic treatment up to 30 h of incubation time (18 wt.% of aragonite for water without magnetic treatment and 38 wt.% for water with an incubation time of 30 h). For incubation times greater than 30 h and up to 200 h the aragonite contain fluctuated about 35 wt.%. The electrochemical corrosion behavior was evaluated using polarization curves (ASTM G5-94). The polarization curves showed that the rate of corrosion increase with the magnetic water treatment.
