Influence of magnetic treatment with superconducting magnet on corrosion inhibition of iron in flowing water

Abstract

The corrosion of iron plates in flowing water has been more inhibited by applying a magnetic flux density of 7.0 T with a superconducting magnet than in the case of non-magnetic treatment (NMT). X-ray diffraction (XRD) quantitative analysis has supported that magnetic treatment (MT) of flowing water is effective for increasing amount of amorphous or nanocrystalline rusts which may be helpful for inhibition of rusting. Experimental results with a monitor of inside of pipes in which water flows in both NMT and MT cases have shown that sticking of iron rust to inside of pipe is more suppressed in the MT case.
