In this study, different sets of plasma-sprayed YSZ thermal barrier coatings were deposited via Ar/H2 and N2/H2 plasmas and compared based on deposition efficiency (DE), thermal conductivity (TC), and furnace cycle testing (FCT). The top-performing coatings exhibited equivalent FCT lifetimes with TC values in the range of 1.15-1.25 W/mK at 1200 °C, but the deposition efficiency of those produced with N2/H2 plasma was twice as high, resulting in a 55% reduction in production costs.
