title = "Degradation of aluminide coatings in Fe-Al-Cr alloy on the isothermal oxidation",
abstract = "Fe base superalloy has a good mechanical strength to be used as component operating at high temperature with oxidative environment. Although, the oxidation rate can not be tolerated as it will be oxidized and form oxide scale of un-protective FeO. Coating is a proper solution that this alloy can be used at high temperature. In this research, pack aluminizing on sample was conducted with temperatures of 900°C, 1000°C and 1100°C for 10 hours in inert (argon) environment and then an oxidation test was carried out at temperature of 650°C by an isothermal method for 10 hours in air environment. It was carried out an analysis for characteristics of coating and oxide scale formed in Fe-Al-Cr super alloy resulted from pack aluminizing. From this experiment, it was indicated by XRD analysis that the coating formed on substrate was a layer of FeAl2 compound, other than coating it was found a diffused zone, where in this area it occurred movement of Fe and Cr atoms from substrate toward coating, while Al atoms moved from coating to substrate. The increase of temperature of pack aluminizing process will affect settling rate of Al and coating growth.",
