PROCEDURE FOR MANUFACTURE OF HEAT RESISTANT COATING ON BLADES OF TURBINES OF GAS-TURBINE ENGINES AND POWER INSTALLATIONS Russian patent published in 2011 - IPC C23C14/48 C23C14/24 

FIELD: machine building.

SUBSTANCE: procedure consists in ion-implantation treatment of blade surface, in vacuum plasma application of heat resistant layer on blade and in successive heat treatment of coating. Ion-implantation treatment of blade surface is carried out with ions of at least one of elements N, Pd, Ag, Nb, Pt, Yb, Y, La, Hf, Cr, Si. The heat resistant layer is applied of alloy of composition: Si - from 4.0 % to 12. 0 %; Y - from 1.0 to 2.0 %; Al - the rest in medium of nitrogen in vacuum not worse, than 10^-3 mm murc. col. and at periodic implantation with ions of at least one of elements Nb, Pt, Yb, Y, La, Hf, Cr, Si, Pd, Ag with manufacture of heat resistant micro- and nano layers divided with implanted micro- and nano layers.

EFFECT: raised heat resistance of coating at simultaneous increased durability and cyclic hardness of coated parts.
