Investigation of Ni-Mo-P Coating Electrodeposition under Stabilized Magnetic Field and its Hydrogen Evolution Activity

Article Preview

Abstract:

Through the application of parallel and vertical magnetic field, which range from 0T to 1.0T, the effects of electromagnetic field in electrodepositon process to prepare Ni-Mo-P coating on its micro-morphology, alloying component, crystal structure and hydrogen evolution activity were investigated. The results showed that the surface of Ni-Mo-P coating obtained was smooth with less ball cellular depositions under an external vertical magnetic field. The coating showed more ball cellular depositions, and the number of which increased gradually with the increasing of the magnetic field intensity under an external parallel magnetic field. The content of Mo increased slightly and the plating structure has switched from transition state into the amorphous state with applied magnetic field. Ni-Mo-P coating obtained with parallel magnetic field had the highest hydrogen evolution activity, while the hydrogen evolution activity decreased under Vertical magnetic field.
