Abstract:
1. A method for depositing a coating on metal machine parts, the coating comprising a plurality of layers, wherein said layers comprise at least one of each of the following: an intermetallic compound (IM) comprised of aluminides of at least one of Ni, Co or Fe, a multiple-component alloy (MCA), oxides and transitional layers of implanted atoms (TM); the method comprising the following steps: 1. cleaning a surface to be coated by ion-plasma etching or sputtering by an ion source; 2. modifying the surface to be coated; 3. depositing a multiple-component alloy to a thickness of 20–60 microns; 4. forming at least one of the transitional layers by ion implantation; 5. effecting ion-plasma deposition of a layer of said intermetallic compound; 6. forming additional transitional layers by ion agitation; 7. forming an oxide layer by depositing a ceramics layer and performing electron beam evaporation of said ceramics layer; 8. annealing in a controlled atmosphere or in a vacuum with a residual pressure of oxygen; and 9. modifying an outer surface of the coating with implantation,
