FIELD: machine building.
SUBSTANCE: proposed method comprises ion-plasma preparation and ion-implanting vane surface treatment, and vacuum-plasma application of heat-resisting layer. Ion-implanting treatment of vane surface is performed by ions of one or several elements selected from Nb, Pt, YB, Y, La, Hf, Cr, Si. Note here that following material for producing inner heat-resisting layer is used with composition that follows in wt %: Cr - 18-30, Al - 5-13, Y - 0.2-0.65, Ni making the rest. Note here that following material for producing outer heat-resisting layer is used with composition that follows in wt %: Si - 4.0-12.0, Y - 1.0-2.0, Al making the rest. Note here that application of outer heat-resisting layer is alternated with periodic implantation by ions of one or several elements Nb, Pt, Yb, Y, La, Hf, Cr, Si to make said outer heat-resisting layer made up of micro layers separated be implanted micro- or nano-layers.
EFFECT: higher heat resistance, longer life and higher cyclic strength.
