<p>A method is provided for improving the corrosion resistance of superalloy substrates, such as gas turbine blades, by initially coating the superalloy with an intermediate bonding alloy, followed by plasma spraying the resulting treated surface with cerium oxide or a sprayable blend of cerium oxide and zirconium oxide. The resulting metal oxide-super alloy composite has been found to be resistant to vanadium and sulfur dioxide corrosion.</p> |
