The aim of this study is the investigation of the effect of ferroboron and ferrochromium with massive wire based hardfacing alloys. Mixture of Fe-Cr and Fe-B powders was added to massive wire during welding process. Hardface layers were obtained by three different powder mixture and three different powder/massive wire proportions. Hardfacing was applied to two AISI 1020 steel substrates by open arc welding. Hardness test, scanning electron microscope and X-ray diffraction analysis were made to the samples. Test results showed that increasing ferroboron content and increasing powder mixture amount enhanced the microhardness of the specimens.
