Abstract

Results are presented of in-situ nucleation and growth studies obtained in a range of gases using an optical microscope fitted with a high temperature environmental cell. In addition to the direct observation of corrosion events as they occur, specimens have been quenched at critical stages of the corrosion process thereby freezing key events for further in-depth examination using more sophisticated techniques. Several examples are given illustrating the usefulness of this relatively simple technique for studies involving metallic and ceramic materials exposed to a range of reducing and oxidizing gas mixtures, which, in some instances, are explosive and/or toxic. Events occurring at temperatures up to 1150 C have been observed and recorded using a video camera.
