0.15 mm vs. 2000 degrees Celsius. Who wins? The answer is in this meditation video. The video shows the process of applying a special ceramic coating on gas turbine engine blades using electron beam evaporation. The thickness of the layer is only a few human hairs, or 0.15 mm. But this microscopic film receives all the thermal shock at 1800-2000 degrees Celsius. By the way, this indicator exceeds the melting point of the metal from which they are made.
