METHOD OF PROTECTING GAS TURBINE PARTS FROM NICKEL ALLOYS Russian patent published in 2012 - IPC C23C14/06

Abstract RU 2452793 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises sequential deposition in vacuum of first layer of condensed coat from nickel alloy on part outer surface and second aluminium-based layer to be annealed in vacuum. Said first layer contains the following elements, in wt %: chromium - 6-12.0, aluminium - 6-12.0, yttrium - 0.1-0.15, tantalum - 1.5-8.0, rhenium -0.3-2.5, hafnium - 0.2-1.5, nickel making the rest.

EFFECT: higher heat resistance at operating temperatures.
