Neodymium iron boron magnet raw material powder and treatment process therefor

The invention provides neodymium iron boron magnet raw material powder. The neodymium iron boron magnet raw material powder comprises neodymium iron boron raw material thin powder and a nickel layer coating the surface of the neodymium iron boron raw material thin powder. According to the treatment process, the milled neodymium iron boron magnet raw material powder is adopted; the powder milled by an airflow mill is directly coated and plated with nickel; the surfaces of the powder granules are coated with a nano-scale nickel-plated layer, so that the oxidization resistance of the neodymium iron boron powder is improved, granular groups formed by powder agglomeration are prevented in the subsequent process, the orientated forming of the powder is facilitated, and the corrosion resistance of the sintered neodymium iron boron magnet is greatly improved.
