The commonly used thermal barrier coating material is the yttria-stabilized zirconia (YSZ) that has resistance to thermal fatigue and thermal shock up to over 1150oC. YSZ is deposited by spraying plasma and a physical beam of electrons vapor deposition processes (Chen and Dong 380). The material can be deposited by HVOF of the spraying applications like blade tip prevention wear, where the resistant properties to wear of the material are also used. In common practice to pre-coat or aluminize the substance material with says MCrAIY bond-coat.

The bond coat is essential to accommodate the residual stresses, which might otherwise develop in the insulating system. This residual stress is caused by the initial metallic substance, and the ceramic material has different coefficients of thermal expansion. Thermal barrier coatings are an advanced system of elements that when applied to metallic surfaces they form a heat management mechanism. They have the capability of shielding the inner surfaces from greater heat loads due to their thermally insulating properties. The coating gives the allowance of operation at high temperatures and limits the exposure to the thermal covered surface. The coating extends the life of the covered surface by the reduction of heat fatigue and reduction of oxidation (Chen and Dong 382). Together with the active film cooling, the thermal barrier coating allows the working fluid temperatures to be higher than the temperature of the metal’s melting of the aerofoil in the turbine. The thermal barrier coating has four layers. metal bond coat, the metal substrate, ceramic topcoat, and the thermally grown oxide. The ceramic part has yttria-stabilized that is used due to its low conductivity and remains stable at the optimum operating temperature typically seen in applications. Recent developments in the seeking for an alternative for YSZ there was the establishment of ceramic topcoat, where different novel ceramics has superior workability at high temperatures of above 1200 0C, where has inferior&nbsp.fracture toughness as compared to the YSZ.
