Coating and Plating
The anti-corrosion ability of NdFeB is very poor because the Nd-rich phase in sintered NdFeB is prone to oxidation, which eventually leads to the powder frothing of sintered NdFeB products, so the sintered NdFeB needs to be plated or coated with anti-oxidation layer to prevent the products from direct contact with the atmosphere.
The commonly used plating layers for sintered NdFeB are Zn, Ni, and NiCuNi, etc., which need to be passivated and plated before plating.
