METHOD OF TREATMENT OF TURBOMACHINES BLADES Russian patent published in 2009 - IPC C23C14/06 C23C14/48 F01D5/28 

FIELD: metallurgy industry.

SUBSTANCE: invention refers to mechanical engineering and may be used in aircraft engine manufacturing and energy turbine manufacturing. Implantation of ions of one of the following chemical elements Cr, Y, Yb, C, B, Zr, N or their combination is performed with further application of multilayer coating with alternate layers (Ti-TiN-Ti-TiAIN) or (Zr-ZrN-Ti-TiAIN) or (Cr-CrN-Ti-TiAIN) or (Zr-ZrN-TiAlN) or (Zr-TiAlN-Ti-ZrN) in vacuum, at that number of layers is 12-1560. In particular cases of invention performance thickness of coating layer is from 10 nm to 2 mcm at general thickness of coating from 5 mcm to 30 mcm. After application of each layer of metal or coating, ion implantation is performed. Application of each layer of coating is performed simultaneously with ion implantation by alloying ions N, Cr, Y, Yb, C, B, Zr. Ion implantation is performed at ions energy 300-1000 eV and ions implantation dose 10¹⁰ to 5·10²⁰ ion/cm².

EFFECT: improvement of coating resistance to salt corrosion, dust and drop-impact corrosion with simultaneous improvement of endurance, cyclical strength and decrease of labor intensity during implementation.
