HARDFACING COMPOSITIONS INCLUDING RUTHENIUM, EARTH-BORING TOOLS HAVING SUCH HARDFACING, AND RELATED METHODS |
摘要 |
Hardfacing compositions include grains of hard material embedded within a cobalt-based metal alloy that includes ruthenium. Earth-boring tools include such hardfacing compositions on one or more surfaces thereof. Methods of applying hardfacing to an earth-boring tool include embedding grains of hard material in a molten cobalt-based metal alloy including ruthenium on a surface of an earth-boring tool, and cooling and solidifying the molten cobalt-based metal alloy with the grains of hard material embedded therein. |
