A novel thermal barrier coating (TBC) material, strontium zirconate SrZrO3, was sprayed by a high feedrate water-stabilized plasma torch WSP 500. Stainless steel coupons were used as substrates. Coatings with a thickness of about 1.2 mm were produced, whereas the substrates were preheated over 450 C. The torch worked at 150 kW power and was able to spray SrZrO3 with a high spray rate over 10 kg per hour. Microstructure and microhardness, phase composition, adhesion, thermal conductivity and
thermal expansion were evaluated. The coating has low thermal conductivity under 1 W/m K in the interval from room temperature up to 1200 oC. Its crystallite size is slightly over 400 nm and thermal expansion 12.3 lm K-1 in the similar temperature range.
