We will also look at what tests that can be. The degradation of polymer composites may be aggravated due to the interaction of a ceramic filler with polymer molecules in the presence of thermal energy from working environments.

Water can dissolve or deform ceramics that have been low fired i e. The susceptibility of a polymer to thermal degradation is a function of the bond strength rodriguez 1970. Phase diagrams thermal expansion and barrier coating degradation august 11 2020 jonathon foreman image above understanding damage caused by environmental silicate contamination to thermal and environmental barrier coatings is important to better protecting turbine blades made from ceramic matrix composites. Therefore to understand the performances of plasma spray ceramic coatings several investigations concerning degradation characteristics including tribological characters and sdhesive strength have been conducted in recent years 3 4.

The thermal stability of high performance polymers in an inert atmosphere are generally very good due to their highly crosslinked and aromatic nature.
