Different mechanisms of failure can be induced and studied with the experimental setup for thermal‐cycling tests developed by the authors and shown in the Figure. It offers a realistic test rig for a broad range of applications, being suitable for a large surface temperature range (1050–1400 °C) and thermal gradients of 0.4–1.0 K/μm through the ceramic layer. Cycle lengths are variable; typically, 5 min heating and 2 min cooling are chosen, since a steady state is normally reached after about 1 min of heating or cooling.
