Abstract

Melt-infiltrated ceramic matrix composite SiC/SiC material systems are under development for use in combustor liners for lowemission advanced gas turbines. Uncertainty in repeatability of processing methods for these large components (33-76 cm diameter), and hence possible reduced reliability for the end user, requires that appropriate test methods, at both meso- and micro-scale, be used to ensure that the liners are acceptable for use. Nondestructive evaluation (NDE) methods, if demonstrated to reliably detect changes caused by processing, would be of significant benefit to both manufacturer and end user. This paper describes the NDE methods and their applications in detecting a process upset in a melt-infiltrated 33 cm combustor liner and how high-resolution scanning electron microscopy was used to verify the NDE data.
