Inside a combustion chamber on a gas turbine engine in aircrafts at duty exist very aggressive corrosive agents. One of these is sulphur, which can deteriorate the materials and reduce their useful life. In this paper the superalloy Haynes 230 oxidation kinect was determined by thermogravimetry in temperatures range of 600- 800 °C exposed for 24 hrs in a O2/SO2 mix environment. Gain weight vs time, transversal morphology of the corroded specimen and characterization by scanning electronic microscope (SEM) were determined. The superalloy Haynes 230 in such conditions obey a parabolic kinetic oxidation.
