  2. Thermal history coating - Wikipedia

    en.wikipedia.org/wiki/Thermal_history_coating

    THCs are applied by atmospheric plasma spraying, which is a thermal spraying technique. This ensures that the coatings are robust to allow long life-times in harsh environments, such as on jet engine components, which experience temperatures in excess of 1000 °C [2] and angular velocities of up to 10,000rpm [3] (revolutions per minute).
