摘要：New cobalt-base wrought alloys containing 24-32% chromium, 14- 22% nickel, 2-8% tantalum, 0.02-0.75% cerium and 0.03%-0.10% carbon have an unique combination ofhigh temperature strength, hot corrosion resistance, oxidation-resistance and resistanceto thermal fatigue cracking are useful in making weld repairs of cracked nozzles of gasturbine engines, as protective coatings for hot stage components of such engines andother similar purposes.
