The aim of this work was to investigate the electrical behavior of AISI 430 ferritic stainless steel which was coated in a Mn-base pack mixture by pack cementation method. Area-specific resistance (ASR) of the coated substrates was tested as a function of temperature by annealing the samples from room temperature to 700ºC. Also ASR has been investigated as a function of oxidation time during isothermal oxidation at 700ºC. Results showed the increase of temperature redounded to the higher values of ASR and also, the coating layer transformed to Mn3O4 and MnFe2O4 spinels during annealing in isothermal oxidation. These spinels caused to decrease the ASR values for coated substrates (14.38 mWcm2) compared to uncoated substrates (31.25 mWcm2) after 200 h isothermal oxidation.
