Thesis title: Ultra-High Temperature Ceramic Surface Coatings for Hypersonic and Space Applications
This thesis is focussed on Ultra High Temperature Ceramic (UHTC) surface coatings, specifically the differing types of UHTC materials that can be applied as surface coatings and the methods that can be used to deposit these materials as coatings. At hypersonic flight speeds and during atmospheric exit and re-entry the surface temperature of aircrafts and rockets can exceed the melting temperature of several compounds utilized in the construction of the craft causing catastrophic failure. Thermal barriers coatings, which are surface coatings typically made from UHTC materials, consist of a thin layer of heat resistant material that can protect components and structures in high temperature environments. Additionally, these coatings can be utilized to conduct heat away from vital areas such as the wing leading edge and nose of a craft, which experience the highest temperatures during operation. As such the goal of this research thesis is to determine the optimal combination of coating configuration, materials (composite coatings) and deposition processes that produce the most effective protective coating.
