METHOD OF PREPARATION OF QUASI-CRYSTALLINE FILMS ON BASIS OF ALUMINIUM Russian patent published in 2008 - IPC C23C14/06 C22C21/00 C23C14/35 C23C14/58 

FIELD: technological processes.

SUBSTANCE: invention is related to methods of quasi-crystalline materials, particularly films of Al-Pd-Re, Al-Fe-Cu composition that might be used due to their unique qualities in bearings, applied as protective coatings in different fields of machine building, aircraft industry and reactor building. Layerwise application of materials is carried out by method of cathode spraying in Penning cell. Number of sections and materials of cell cathodes are selected in accordance with composition of quasi-crystalline film. Then protective coating AI₂O₃ is applied and vacuum annealing is carried out. Total thickness of quasi-crystalline film is formed at the account of thickness change and total quantity of applied layers. As materials that are applied together with aluminium_, materials from the following groups are selected: Cu, Fe, Cr, Co, V, Ni, Ti, Mn, Pd, Ru, Re, Rh, Tr, Mn, Mo, Os, Si, Mg, Li.

EFFECT: preparation of quasi-crystalline films of stable composition, which possess high technological properties - electric conductivity, heat conductivity and solidity.
