Rocket thermal barrier coatings. Wear resistant & anti friction coatings.

Thermal barrier coatings are state of the art and this concept should be transferred to copper substrates in rocket engine applications. For optimization of a suitable coating, a material system known for gas turbines is employed. In this work a thermal barrier coating system is applied by atmospheric plasma spraying to the copper-based high strength. The coating system is tested in thermal cycling experiments, where no failure of the coating could be detected.
