Abstract

A high activity aluminide coating was formed on the γ phase Inconel 625 superalloy by the pack cementation process. Transmission electron microscopy was used to investigate the structure of the transient oxides formed on the aluminide coating. The transient oxides formed on the coating after exposure in air at 1200 °C for 250 s were found to consist of highly oriented NiO, Ni(Al, Cr)2O4 and α-(Al, Cr)2O3. © 1987.
