▎ 摘　　要

NOVELTY - Corrosion-resistant neodymium-iron-boron (NdFeB) material comprises graphene oxide layer at the grain boundary on the surface of the NdFeB substrate. USE - Used as corrosion-resistant neodymium-iron-boron material. ADVANTAGE - The corrosion resistant neodymium iron boron material has excellent corrosion resistance, and reduces the brittleness of the sintered neodymicron-iron-boron material, so as to reduce the knock-off ratio, and improves the quality of the permanent magnet material by permeating into multilayer two-dimensional graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: izing agent for the corrosion resistance neodymium iron boron material; lurry for corrosion resistance; and preparation method of the corrosion resistance.
