Technological developments create harsh environmental operating conditions such as high temperature, mechanical loading, oxidation, corrosion, and erosion. Metals may not provide the necessary
properties for operating conditions in which a ceramic (oxide and nitride) is deposited on a substrate as
a protective layer. Ceramic materials have been used in many high-temperature applications as
refractors owing to their high melting temperature. These refractor ceramic materials need to have
basic properties, phase stability at a high temperature, a high thermal expansion coefficient, and low
thermal conductivity. Elevated pressure turbine blades are one of the biggest challenges engineers need
to overcome. Today, they can resist gas temperatures higher than the melting point of the underlying
substrate metal. This phenomenon would not have been possible if it were not for the ultimate strength
of superalloys and the development of coatings. Also, the isolation of metallic substrates provides the
ability to work in higher temperature close to the melting point of the substrate. Thermal barrier
coatings (TBCs) were first used for aerospace applications. Calcia-stabilized zirconia and frit enamels
were deposited onto the exh
