High Temperature Oxidation Group Facilities

Specialised equipment includes

  • A  six-station thermobalance facility capable of undertaking oxidation exposures at temperatures to 1400°C whilst continuously monitoring specimen mass.  As well as in-situ mass change kinetics this equipment is used to determine the critical temperature drop during cooling to produce loss of surface oxide. The results have provided valuable insights into the oxide spallation process.
  • Constant stress creep rigs in both tension and compression.  Using these rigs a unique technique was developed to determine the creep properties of a number of high temperature oxidation resistant coatings.
  • Static furnaces.  These are the work horses of much of the oxidation testing under isothermal conditions.
  • Thermal cycling furnace capable of simulating operational thermal cycling conditions found in engines.

As part of the School of Metallurgy and Materials, the group has access to a large selection of characterisation tools:

The I11 beam has been used several times by our group to examine thin surface oxides formed during the early stages in the oxidation process.  The high resolution XRD data provided by this facility has provided great insight into the oxide phases formed within the first hours of oxidation.
