Enhanced bonding stability of Fe oxide layer on low carbon steel via low-pressure air oxidation

Journal of Materials Research and Technology
The oxidation behavior of low carbon steel (SS400) was investigated at 500 °C under different air pressures: 1 atm, 1/10,000 atm, and 1/50,000 atm. The results showed that the oxide growth rate at 1/10,000 atm was higher than at atmospheric pressure ...
