Zusammenfassung:	The present disclosure relates to methods for coating gas turbine engine components, such as combustor panels. In one embodiment, a method includes forming a first layer to a substrate to form a bond coat, and forming a second layer over the first layer. The second layer may be formed by a material having a thermal conductivity within the range of 4.45 to 30 Kcal/(m hoC). According to one or more embodiments, the first layer may be formed by at least one of a high velocity oxy-fuel (HVOF) source, an electric-arc source and low pressure plasma spraying. According to one or more embodiments, the second layer, and as a result a thermal barrier coating, may be formed by at least one of air plasma spraying, suspension plasma spraying, and electronic beam physical vapor deposition.
