Study of hardness and microstructure of Fe-C-Si-Mn-B hardfacing alloy

Iron based alloys are normally utilized for abrasive coatings to resist wear. Chromium added iron alloys are commonly chosen for hardfacing, which is one of the surface improvement methods. Such alloys are costly and give a moderate hardness to the deposits, due to the large addition of chromium. Fe...
