Process for protecting the surfaces of shaped superalloys against oxidation and corrosion |
| abstract |
The invention relates to a method for improving the corrosion resistance of superalloy substrates, such as gas turbine blades, wherein the superalloy is initially provided with an intermediate bonding layer, followed by plasma spraying of the resulting treated surface with cerium oxide or a sprayable mixture of cerium oxide and zirconium oxide. The resulting metal oxide superalloy composite was found to be resistant to corrosion by vanadium and sulfur dioxide. |
