Abstract: A method of producing an oxide dispersion strengthened nickel-base superalloy, comprising introducing an oxide dispersoid material into a plasma gun of a plasma spray apparatus, where it is sublimed and turned to vapour; and introducing a nickel-base superalloy material into the plasma spray apparatus at a cooler location, downstream of the plasma gun, such that the oxide dispersoid material condenses on the superalloy material to produce the oxide dispersion strengthened nickel-base superalloy.
