Principal drawback of graphite for use as rocket nozzle throat insert is its erosivity; erosion of inserts is explained on basis of chemical mechanism if account is taken of chemical composition of exhaust stream, geometrical and temperature history of insert, ballistic effects of erosion, rates of diffusion of molecular species through boundary layer, and chemical kinetics of surface reactions; results of erosion calculation.
