Investigation on the Interfacial Bonding Strength between Ni-P-W/Al₂O₃ Composite Coatings and NdFeB Matrix

Abstract:

¹̄The Ni-P-W/Al₂O₃ composite coatings were deposited on the NdFeB magnetic materials surface by electroless plating method. The morphology of Ni-P-W/Al₂O₃ coatings was investigated using scanning electron microscopy. And the X-ray diffraction was used to identify the phase constituents. The interfacial bonding strength between Ni-P-W/Al₂O₃ composite coatings and NdFeB matrix was also tested. The results indicated that the interfacial bonding strength is prone to be increased while the Al₂O₃ powders co-deposited with Ni-P-W coatings. And the interfacial bonding strength would reach the highest value when the Al₂O₃ concentration is in rang of 5gL^-1 to 10gL^-1.
