Abstract

Nano composite coatings of the intermetallic compound Fe-Al/Cr

were prepared and their high-temperature corrosion resistance was tested

in order to overcome the corrosion problems of easily corroded parts in power plants by thermal spraying. Using the reunion-granulation system we developed independently

highly active nano Fe-Al/Cr

composite spraying materials successfully underwent reunion-granulation. High-velocity flame spraying was employed to spray the nano Fe-Al/Cr

composite coating on the structural materials. The high-temperature corrosion resistance of the micro and nano Fe-Al/Cr

composite coatings was tested under the same corrosion conditions. Parabolic and power function curves were used to fit the corrosion kinetic curves. The particle sizes of the Fe-Al/Cr

composite spraying materials changed from the nanometer scale to the micrometer scale. Post reunion-granulation

the nano-sprayed particles were spherical or elliptical

the chemical composition of the granulated particles was the same as that of the original

and the inner granulated particles maintained their nanometer sizes. The surface of the nano Fe-Al/Cr

composite coating was compact

and the spreading is uniform. The element transition of section is smooth and the layer is fine. The power function curves fit the corrosion kinetic equation better. The corrosion rates of the coatings were calculated by deriving the fitted corrosion kinetic equation. The characteristics of the nano-sprayed particles meet the relevant requirements after reunion-granulation. The high-temperature corrosion resistance of the nano Fe-Al/Cr

composite coating was significantly better than that of the micro coating. The mechanism by which the nano chromium and aluminum are preferentially oxidized and form protective oxide layers explains the excellent high-temperature corrosion resistance of the nano coating.
