The thermal sprayed coatings consists mainly of solid matrix and pores formed in the matrix. This porosity and different phases in solid matrix will influence thermal conductivity of coating. Thermal properties in thermal sprayed coating are important to determine as application for thermal barrier. Thermal barrier coating should have the thermal conductivity as low as possible. This paper was investigated the characteristics of the thermal sprayed coating, especially the thermal conductivity of four kinds of NiAl+Al_2O_3 coatings. Objective of this work is to find the thermal properties different from porosity.
