FIELD: metallurgy.
SUBSTANCE: packing coating for modification of power turbine stator element contains, wt %: boron nitride - 2-5, polyvinyl alcohol - 7-10, stabilised by yttrium oxide zirconium dioxide of the system ZrO2 - 7-9% Y2O3 - the rest up to 100%. The ratio of the boron nitride contents to the polyvinyl alcohol content amounts 1:2.
EFFECT: improvement of coating quality, high porosity without laminations and cracks in the coating.
