SAFETY METHOD AGAINST HIGH-TEMPERATURE OXIDATION OF INTERNAL CAVITY SURFACE OF COOLED TURBINE BLADES MADE OF CARBON-FREE HEAT-RESISTANCE ALLOY ON BASIS OF NICKEL |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: it is implemented coating of internal cavity of blade by carbon with saturation rate from 1.5 till 8 g/m2 by means of filling of internal cavity of blade by powder mixture or gaseous medium, heating or isolation of blade with filled internal cavity. Then it is implemented application of diffusion aluminide coating with saturation rate from 15 till 60 g/m2. ^ EFFECT: high-temperature coat for protection against high-temperature oxidation of internal cavity surface of turbine blade. ^ 3 cl, 1 tbl, 2 ex |
