Understanding the Sintering Behavior and its effect on the thermal conductivity of YSZ Coatings for Gas Turbine Applications

Thermal barrier coatings are essential to protect the combustion chamber liner material from harsh environments in modern gas turbines that used aerospace and land-based power generation facilities. As there several different materials produce thermal coatings, conventional coating is yttria stabilized zirconia (YSZ). The most common method manufacture YSZ plasma spraying due its flexibility rapid production capacity. Using spraying, often requires understanding process parameters effect on structure. many control main outcome of all particle temperature velocity during hence properties such as hardness, porosity ratio deposition rates. Furthermore not only produced microstructure but also service conditions sintering behaviour be considered. Sintering results declining their insulation properties. Therefore, this study we have evaluated conductivity sprayed coatings. To achieve objective, free-standing subjected them heat treatment, followed by measurements conductivities. will contribute a better impact performance
