METHOD FOR OBTAINING PROTECTIVE NANOCOMPOSITE COATING ON ALUMINIUM OR ITS ALLOY

摘要

1. A process for preparing a nanocomposite protective coatings on aluminum or its alloy comprising aluminum and mixing powders of metal oxides in stoichiometric amounts, applying the mixture of powders in aluminum or its alloy surface and holding aluminothermic reaction of said powders, characterized in that aluminum powder is used as stabilized nanosized alumina powder having a particle size of 3 to 100 nm, and as the metal oxide powder - nanoparticulate metal oxide powders with particle size of 5 to 100 nm in stoichiometric amounts. ! 2. A method according to claim 1, characterized in that the aluminothermic reaction is carried out in the presence of an initiator, which is used as stabilized magnesium nanosized powder with the following component ratio (aluminum oxide + metal) / Mg = 10 / (1-10).
