Abstract : Data generated using laboratory tests such as oxidation-erosion, thermal fatigue, ballistic impact, and wear-galling to simulate turbine engine environments are reported for eight coated columbium alloy composites. Applications considered were turbine vane and turbine blade airfoils operating in the 1800-2500 F temperature range and turbine blade roots at 1300-1600 F.
