High temperature oxidation of metals and materials occurs when the tempCopper colour changing due to formation of oxideerature is sufficient to allow interdiffusion of metal and oxygen. It can be deliberate:

  • Furnace produced coloured metal for controlled heat transfer characteristics (emissivity).
  • Growing a certain layer thicknesses of silicon oxide insulation or silicon oxynitride as a dielectric on semiconductor wafers.
  • Furnace oxidation method of cleaning organic contaminants off metals prior to thermal reduction.
  • FTIR oxide thickness measurements

In other cases oxidation is to be avoided or only permitted until a protective oxide is produced. Areas of interest may be:

  • Inside a power generation gas tubine or aircraft jet engine.
  • Automotive engine components.
  • Air leaks in a reducing or other gas furnace process such as hardening or annealing.
  • Welding under a protective inert gas shield and high temperature.

Surface oxidation can be evaluated by a combination of surface analysis techniques like XPS and SEM/EDX. The laboratory also has facilities to mimic thermal processes under a range of reducing and oxidising gas environments.
