In this method, commercial Ekabor-II powders were thoroughly mixed with ferro-silicon powders to form the boronising medium. The samples were boronised in an electrical resistance furnace for 5 h at 1173 K under atmospheric pressure. The results showed that borosilicide and boride layers were formed on the surface of boronised permalloys, with average hardness of 900-1000 HV0.1. The average thickness of the multilayer coating was 90 mu m, and did not show significant change with Ni content within the range studied. The saw-tooth morphology of the boride layers were smoothened with increasing nickel content.eninfo:eu-repo/semantics/closedAccessPermalloysBoronisingBoride LayerBorosilicide PhaseHardnessArticle2-s2.0-85058802130
