  • Cobalt-base wrought alloy compositions and articles
    Patent number: 5192625
    Abstract: 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 of high temperature strength, hot corrosion resistance, oxidation-resistance and resistance to thermal fatigue cracking are useful in making weld repairs of cracked nozzles of gas turbine engines, as protective coatings for hot stage components of such engines and other similar purposes.
