Özet

Ferrochromium is used in hardfacing alloys as carbide former. In this study, ferroboron was used with ferrochromium to investigate the effect on microstructure and wear resistance. Five different hardfacing alloys (50 % massive welding wire + 50 % powder mixture) were produced by open arc welding on AISI 1020 steel. Microstructure, SEM and XRD analysis, hardness test, and dry sand/rubber wheel abrasion test were carried out. According to the test results, as the amount of ferroboron increased, wear rate decreased. Minimum wear rate was obtained in 100 % ferroboron powder added sample.
