Abstract EN
A series of experiments have been conducted to study the resistance of isothermal oxidation in 69.5Fe-14Ni-9Al-7.5Cr (% wt) alloys with some temperature variations of 800, 900, and 1000°C and each temperature is tested for 1, 10, 50, and 150 hours.
Based on the analysis conducted on the test results, it is known that the higher the oxidation temperature, the faster the oxidation rate.
As for the duration of oxidation, the longer the testing time is, the smaller the weight change per unit sample area is, indicated by a sloping graph.
The oxide products found in this study were Fe2O3, Fe3O4, α-Al2O3, NiO, Cr2O3, and NiCr2O4.
The rate of oxidation of this alloy at each temperature follows a logarithmic equation indicating that the oxide layer formed is very thin and can protect the metal surface well.
The oxidation rate constants at temperatures of 800, 900, and 1000°C are 5.15E-05, 5.57E-05, and 6.74E-05 gr.cm−2, respectively.
