Abstract
Young's modulus of CVD and SiC coatings was measured in situ (on the s ubstrate) using strain gage/flexure and dynamic resonance techniques. The average Young's moduli of CVD SiC from these techniques were 446 a nd 415 GPa, respectively, and were considered to be in good agreement. The determination of a representative coating thickness and cross sec tion is critical in order to accurately estimate Young's modulus of co atings.
