Abstract: The B-Al permeation layers of Steel 45 were studied by means of SEM, TEM and XRD.The formation and growth model of permeation layer was proposed.The layer formation,growth and the migration behaviors of B were discussed.It is suggested that the diffusion of Al is deferred when the surface was covered by borides and aluminize compounds are surrounded by borides with the further growing of borides.
