There is a desire to use gases derived from increasingly ‘dirty’ fuels (e.g. coal and biomass) in industrial gas turbines. The contaminants in these fuels have the potential to cause significant damage to the gas turbine hot gas path materials, many of which were developed and selected for natural gas fired conditions. This paper reports results of a study investigating the performance of thermal barrier coatings (TBCs) and bond coatings, applied to current industrial gas turbine materials, within clean and ‘dirty’ gas environments generated within a burner rig.The materials covered by this study included: • TBCs based on 8%Y2O3–ZrO2 applied by both air plasma sprayed (APS) and electron beam – physical vapour deposition (EB–PVD) routes.• Bond coats of the overlay and diffusion classes, applied by vacuum plasma spraying (VPS), electroplating (EP), chemical vapour deposition (CVD) and high velocity oxy-fuel (HVOF) spraying• Base alloys of IN6203, CMSX-4 and Haynes 230The required TBC/bond coat combi...
