The development of new ceramic materials to protect the metallic components against corrosion and oxidation at high temperature, also known as thermal barriers coating (TBC), is of a great interest topic for many industrial and consumer sectors, such as energy generation, aeronautics and automotive industries.

This paper carried out a study on the thermal fatigue behavior of the bond coat, by centering the answer in one of the components which constitute a TBC: the anchor coat. The different TBC components were deposited by an Atmospheric Plasma Spraying (APS) Technique. Microstructure and anchor coat composition along the thermal cycles were studied.
