Experienced Hydrogen Consultants and Scientists
Our CTO, Dr. Lasseigne, is a leading hydrogen expert, with a focus on the effects of H2 and H+ in metals. She has experience with hydrogen’s effects in a broad range of areas including: industrial and nuclear metals, welding, fuel cells and battery materials, pipelines, refineries, and power generation. Her hydrogen research and testing work has covered a great number of materials, as well, including steels, titanium, zirconium, reactive metals, nickel lanthanide, sodium alanate, and numerous other materials. The unique and extensive testing she has performed on hydrogen in numerous different materials is providing new insights into its nature and effects.
The Effect of Magnets on Hydrogen
Corrosion differs drastically when an applied magnetic field is used (as on the right) during electrochemical charging in a mild sulfuric acid solution. The real (and incredibly powerful) effect of hydrogen is evident in many materials [1, 2]. For example, in the picture above, there are two specimens, one which had no magnetic field (left) and the other with an applied magnetic field (right), showing the effects of magnetism on hydrogen diffusion into steel. The magnetized sample, on the right, suffered severe corrosion and pitting while the other sample is nearly untouched. In this case, the magnetic field accelerated the corrosion process by increasing the rate of current exchange, resulting in H2 supersaturation that led to both pits and cracks simultaneously forming as shown below.
