Claims (2)

1. Способ изготовления металлокомпозитного материала, отличающийся тем, что он включает в себя следующие операции: растворение по меньшей мере одной органической или неорганической соли металла или соединения по меньшей мере одной из групп IV, V и VI периодической системы элементов, в частности, V, Сr, Мо и W, возможно в сочетании с одной или несколькими органическими солями металла группы железа, по меньшей мере в одном полярном растворителе, и образование комплекса при помощи по меньшей мере одного комплексообразователя, который содержит функциональные группы в виде ОН или NR3 (R = Н или алкил), добавление в раствор твердого образующего порошка и, возможно, растворимого источника углерода, испарение растворителя, проведение термообработки оставшегося порошка в инертной и/или в восстанавливающей атмосфере для получения твердого образующего порошка с покрытием из металлов групп IV, V и VI периодической системы; добавление уплотнителя, одного или в сочетании с другими твердыми образующими порошками с покрытием, для получения желательного состава указанного твердого образующего порошка с покрытием, прессование и спекание.1. A method of manufacturing a metal composite material, characterized in that it includes the following operations: dissolving at least one organic or inorganic metal salt or compounds of at least one of groups IV, V and VI of the periodic system of elements, in particular V, Cr, Mo, and W, possibly in combination with one or more organic metal salts of an iron group, in at least one polar solvent, and complexing with at least one complexing agent that contains tional groups in the form of OH or NR 3, (R = H or alkyl), adding a hard constituent powder solution and optionally, a soluble carbon source, the evaporation of the solvent, conducting the heat treatment of the remaining powder in inert and / or reducing atmosphere to obtain a hard constituent powder coated with metals of groups IV, V and VI of the periodic system; adding a sealant, alone or in combination with other coated solid forming powders, to obtain the desired composition of said coated coated solid forming powder, pressing and sintering. 2. Способ изготовления металлокомпозитного материала по п. 1, отличающийся тем, что уплотнитель в раствор добавляют совместно с твердым образующим порошком и указанным растворимым источником углерода, а затем производят сушку, прессование и спекание, с учетом условий термообработки. 2. A method of manufacturing a metal composite material according to claim 1, characterized in that the sealant is added to the solution together with the solid forming powder and the indicated soluble carbon source, and then drying, pressing and sintering are carried out, taking into account the heat treatment conditions.
