Advanced Materials for Aircraft Propulsion Systems. Phase I. Investigation of Corrosion Resistant Coatings for Service at 3000 F and above.
Abstract
The coatings to be developed are aimed primarily at the most severe environment in a jet engine: namely, turbine vane and blade components, since present NiAl coatings on these components are inadequate above 1800 F. The BCL coating-development work is based on a 3-region composite-coating concept: Region 1 - an outermost corrosion-resistant barrier providing primary environmental protection, Region 2 - a self-healing reservoir, and Region 3 - a diffusion barrier between the coating and metallic substrate. Preliminary studies were limited to development of coatings that would be applicable to the protection of Ni-base and Co-base superalloys. (Author)
