Abstract : A process is described for forming a duplex coating as a fire barrier on a composite structure comprising organic matrices so that the structure shows reduced flammability, less smoke, higher ignition resistance, and more residual flexural strength after exposure to fire. A thin layer of a metal such as zinc is arc wire sprayed onto a surface of the structure to form a bonding and heat-diffusing coating, and a stabilized zirconia coating is then plasma sprayed onto the metal coating to form a thermal barrier coating.
