Effects of a Magnetic Field on Hydrogen Evolution Reaction and its Diffusion in Iron and Steel

摘要

The presence of hydrogen in high strength steels results in catastrophic failure of a part much below its threshold strength. Chemical cleaning, finishing and electroplating processes generally introduce critical amounts of hydrogen in metals. In the present work an attempt has been made to retard hydrogen entry into the metal from such treatments by the use of a magnetic field. Experiments have shown that the effects of an applied magnetic field have affected both the hydrogen evolution reaction process and its diffusion in both Armco iron and high strength 4340 steel.
