Abstract

This research aimed to study the high-temperature oxidation of carbon steel in simulated combustion atmosphere. The comparative oxidation rate of sample substrate carbon steel was experimentally investigated. The comparative high temperature oxidation rate studies were carried out using different atmosphere of gas and salt at 800 °C with different time 1, 25, and 100 hr. The kinetics of oxidation rate of carbon steel were established with weight change measurements. The oxidation rate was measured by the ratio of weight loss and quantity of gas and gas-salt atmosphere. The morphology surface of oxidation in form of spallation and peeling of unprotected oxidation and sulphurization. The structure morphology and chemical composition were characterized by Scanning Electron Microscopy (SEM) and X-ray diffractometry (XRD). The oxidation behavior was further discussed in this research.
