The Fe-Cr alloy was coated with pack boriding method for theduration of 6 h at 800 °C, 900 °C and 1000 °C. Chemical and phase content,microstructure, hardness of the formed boride layer were studied by using XRD,SEM-EDS, microhardness measurement device. Perfect adhesion of coating tosubstrate and formation of compact boride layer composed of Fe2B andCrB phases on the substrate were observed. The increase of temperature resulted in formation of transition zonewith CrB precipitates whose amount increased with temperature. The treatmenttemperature resulted in increasing of main boride coating thickness. Boridelayer hardness was changed between 2500 HV and 3500 HV independent fromboronizing temperature.
