Method of applying cermet coat slurry on turbine stator inner surface / 2433208
Slurry is applied by pouring into stator inner cavity through inlet branch pipe in amount sufficient for complete immersion of guide naves in slurry. Inlet branch pipe is sealed to turn turbine stator about its axis through angle at which inlet branch pipe stays at its bottom position. Then, turbine stator is turned clockwise about axis perpendicular to its axis through angle of inclination to horizon at which slurry does not flows out of turbine stator with inlet branch pipe and guide vanes unsealed. Thereafter, turbine stator is turned about said axis counter clockwise to drain slurry. Now with slurry drained, turbine stator is rotated about its axis with turbine in horizontal position, unless slurry layer water glare disappears.
