Exposure tests

With exposure experiments, the thermochemical stability (corrosion resistance) of materials can be studied under very precisely defined conditions. The thermochemical stability, i.e. the stability of a material in agressive gas atmospheres at high temperatures, is often a basic requirement for its practical application.

Measurements are carried out as a function of temperature, time and gas composition. Analyses of the samples using imaging techniques, scanning electron microscopy and X-rays allow conclusions to be drawn regarding the thermochemical stability of the materials.
