The corrosion apparatus of redundant and composite coating was evaluated by Tafel Polarization scans and adulteration doings was estimated by AC resistor spectroscopy. The coating morphology, climb alchemy and identification of component phases were analyzed by examine electron microscope and X-ray diffraction method respectively. It was deduced that the corrosion reactions of composite surface attractor were controlled by anodic polarization as compared to mere(a) magnet where the degenerative tendency toward corrosion was rapid. The early surface magnet protection was deteriorated by kinetically controlled corrosion reactions as predicted from impedance spectroscopy.

The charismatic properties remained un-affected for both composite coated and bare NdFeB magnets. Keywords: Corrosion, Composite Coatings, NdFeB Magnets, Polarization, ohmic resistance Spectroscopy. introduction For higher energy efficiency and excellent mag netic properties the NdFeB sintered magnets ! occupy leading position among other magnetic materials and considered beat for many applications such as electronics, automotives, aerodynamics, computers, biomedical, acoustics and automation[1-4]. In many studies [5-8] alloying with contrastive rare earth passage metals as partial exchange of Fe and Nd has been investigated to rectify their magnetic and electrochemical immunity.
