Abstract

Disclosed herein are embodiments of hardfacing/hardbanding materials, alloys, or powder compositions that can have low chromium content or be chromium free. In some embodiments, the alloys can contain transition metal borides and borocarbides with a particular metallic component weight percentage. The disclosed alloys can have high hardness and ASTM G65 performance, making them advantageous for hardfacing/hardbanding applications.
