Cover:The electrochemical charging technique has been used to investigate the hydrogen absorption of the sintered NdFeB magnet. The photo shows the surface structure of the sintered NdFeB magnet which was charged with hydrogen at a cathodic current density of 4mA/cm2. The specimen was prepared for studying the exfoliation corrosion mechanism of the sintered NdFeB magnet due to hydrogen absorption. More detailed information can be found in: H. Yang, S. Mao, Z. Song, The effect of absorbed hydrogen on the corrosion behavior of sintered NdFeB magnet, Materials and Corrosion 2012, 63, 292.
