Abstrakt: A Mach 0.3 burner rig test program was conducted to examine the sensitivity of thermal barrier coatings to Na and V contaminated combustion gases simulating potential utility gas turbine environments. Coating life of the standard ZrO-12YO/Ni-16.2Cr5.6Al-0.6Y (composition in weight percent unless stated otherwise) NASA thermal barrier coating system which was developed for aircraft gas turbines was significantly reduced in such environments. Two thermal barrier coating systems, CaSiO/Ni16.2Cr-5.6Al-0.6Y and ZrO-8YO/Ni-16.4Cr-5.1Al-0.15Y and a less insulative cermet coating system, 50 vol pct MgO-50 vol pct Ni-19.6Cr-17.1Al-0.97Y/Ni16.2Cr-5.6Al-0.6Y, were identified as having much improved corrosion resistance compared to the standard coating.
