Thermal Spray - Challenges and Solutions for Sustainable Aviation

Gas turbine engine propulsion solutions will play a fundamental role in the transition to a low carbon economy for the aerospace industry. At Rolls-Royce, the decarbonization strategy is comprised of continued reductions in fuel consumption and emissions, incorporation of sustainable aviation fuels, and the development of innovative power alternatives such as electrification and hydrogen. Coating materials and surface engineering solutions will play a key part in enabling this transition. Challenges include continued dependency on critical raw materials, increasing engine performance requirements in hot and harsh environments, and understanding how coatings will perform within novel propulsion systems. Sustainable manufacturing methods for coatings which reduce energy intensity, emissions, and environmental impacts also require identification and incorporation within operations and the supply chain.
