Analysis by EPMA showed thatthe Y was concentrated in the intermediate zone of the coating as metallic compoundNi_5Y. After exposure to air up to 1000℃, the oxidation tests revealed that theanti-oxidation properties of the yttraluminizing coating with secondary aluminizingare much superior to that with single aluminizing only.
