摘要

•Room temperature atmospheric oxidation behaviour of sintered NdFeB.•3D laser confocal microscopy measurement of oxide phase growth.•Significant height increase of oxide phase only observed at triple points.•Raman spectroscopy identified oxide phase to be Nd2O3.•Diffusion coefficient determined to be 4×10−13cm2/s.
