摘要：A cobalt-based alloy composition having a relatively small lanthanum additionand relatively large carbon content provides remarkable oxidation resistance and wearresistance at high temperatures. The cobalt-based alloy composition has a suitablecombination of ductility and wear resistance at high temperatures to be effective as a
hard face material for limiting the effects of chattering of blades during the operation ofa gas turbine engine. Further, the cobalt-based alloy has a suitable combination ofductility, oxidation resistance and wear resistance and thus represents an improved hardfacing material for the blade components of gas turbine engine.
