Abstract:

An experimental procedure for determining the net residual stress of a typical ICBM coated nozzle throat insert is described. The experiment includes provisions for separating substrate-induced stresses from the primary and secondary coating stresses. The results of such experiments conducted on a pure pyrolytic graphite coated insert and on a codeposited silicon carbide and pyrolytic graphite insert are discussed.
