Effect of sample thickness on the oxidation and carburization kinetics of 9Cr-1Mo steel in high and atmospheric pressure CO2 at 550 °C

The influence of 9Cr-1Mo sample thickness on oxidation and carburization kinetics was investigated. State of the art characterization and modeling techniques were employed to investigate the oxidation and carburization behavior. Within the tested exposure times, the sample thickness did not affect oxidation kinetics, products, or the carburized microstructure. The carburization profile measured by various techniques were in good agreement. From...
