Project Description

The purpose of this project is to develop nondestructive evaluation (NDE) techniques, computed tomography, ultrasonics, X-ray radiography, that can be used to characterize and detect flaws in structural ceramics in the early stages of processing as well as in the final densified state, or those that are currently in use within various processes. Delaminations, thermal shock damage, density gradients, preferred fiber orientation, and fiber/matrix interface conditions are sources of failure in ceramic materials. NDE techniques are needed to characterize the materials and provide the user with a means to be alerted to the potential for failure, prior to it occurring. End-users of such technology will include manufacturers of hot-gas filtration systems and makers of ceramic monolithic and composite hot-gas filters.

Project Benefits

This project will evaluate corrosion and mechanical properties of materials in combustion and mixed-gas environments. Advancements in evaluation of corrosion and mechanical properties will lead to the identification of suitable materials with adequate mechanical properties to solve issues with high-temperature service and a reduction in ASME Boiler and Pressure Vessel Code approval time. Overall, improvement to high-temperature advanced materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, with improved efficiency and operational flexibility, resulting in lower operating costs.
