VAPOR DEPOSITION OF TUNGSTEN ON ROCKET NOZZLE INSERTS
Abstract
A second beryllia nozzle insert was coated with tungsten. The deposited metal was rough and lacked uniformity. This condition was owing, in part, to difficulty in controlling a slow flow rate of heavy-density tungsten hexachloride vapor. The tungsten-coated beryllia substrate had a transverse crack. Beryllia exposed to reactant gases showed some corrosion.
