High temperature materials technology drivers

Technology drivers for the aerospace (gas turbine) industry

Business Drivers	Issues	Technology and Innovation Needs
Markets	Unit cost	Reduced cost materials and processes. Improved welding processes (particularly for dissimilar materials). Improved performance materials
	Time to market	Materials with reduced processing times. Better modelling capability "On -the -shelf " technology
	Weight	Lower density materials.
	More Electric Engine	Improved electrical insulation materials. High performance conductors/ magnetic materials/ electrical components (dielectrics, semiconductors, superconductors).

Quality, reliability and durability	Component lives	More precise component life prediction methods. Improved oxidation/corrosion protective coating materials. Improved material behaviour understanding. Improved understanding of effects of defects. Improved NDE methods.
	Repairability	Develop repair methods for blisks, SX components, etc. Life prediction methods for repaired components.

Environment	Thermal efficiency	High temperature materials Improved oxidation / corrosion resistant coatings. Improved abradable/sealing materials and blade tip treatments.
	Reduced emissions	Higher temperature combustor materials (for casings, liners, tiles, fuel injectors, etc). Improved oxidation/corrosion protective coating materials. Improved thermal barrier coating materials. Development of anti-coking coatings.
	Health & Safety	Less hazardous materials.
