Fig. 5 Micrograph of a typical two-phase NiCoCrAlY low-pressure plasma-sprayed coating after several hours of service. The dark aluminide phase is depleted near the coating surface as the aluminum is consumed to form the thermally grown oxide alumina scale visible under the nickel plating used More
