    Dear Thermal Spray Community!

    Competition Funded PhD Project (Students Worldwide). (A*STAR) A rare earth aluminate thermal barrier coating for prolonged lifetime (University of Manchester - UK).

    Summary: In this project, we will develop a new TBC with higher temperature capability and durability. Instead of carrying on incremental research to modify current TBC materials, we will explore a new material based on gadolinium aluminate, which is a member of the perovskite rare earth aluminate family with high melting temperatures of up to 2500°C. We will first fabricate bulk ceramics and measure a number of thermal and mechanical properties to evaluate the suitability of gadolinium aluminate for TBC applications, including phase stability, coefficient of thermal expansion, fracture toughness, thermal conductivity and resistance to molten silicate attack. We will then manufacture gadolinium aluminate TBCs by air plasma spray and test their performance in simulated engine operating conditions. Failure analysis will be performed to identify failure mechanisms and quantify damage evolution. The thermal and mechanical properties of the coatings will be measured and compared to bulk ceramics to study the effect of microstructure on the properties. We will perform detailed characterizations to develop fundamental understanding of their structure-property relationships. The understanding will provide scientific guidance for optimizing the coating design.
