Abstract
Embodiments of wear resistant ferrous alloys are disclosed herein. In some embodiments, ferrous alloys can have a matrix which includes near spherical and hypereutectic borides and/or borocarbides while at the same time avoiding the formation of rod-like borides and/or borocarbides. In some embodiments, the wear resistant ferrous alloys can be used as a coating, such as a hardfacing layer, to add protection to different components.
