The Versatility of HVOF Burner Rig Testing for Ceramic Matrix Composite Evaluation by Gregory N. Morscher, Ragav P. Panakarajupally, Leland Hoffman

“…Effective testing of ceramic matrix composites (CMCs) and CMC/coating systems for high temperature, high stress, high velocity and/or severe oxidation/corrosion environments is a critical need in materials/coatings evaluation for extreme environments of hot section parts in jet engine and hypersonic applications. Most current technology can evaluate two or three of the extreme conditions for a given application; however, incorporating as many of the extreme thermo-mechanical-environmental factors is highly advantageous to understand combinatorial effects. …”
