摘要

the invention belongs to the field of protective metal coatings on articles made of steel, nonferrous metals and their alloys by u0442u0435u0440u043cu043eu0434u0438u0444u0444u0443u0437u0438u043eu043du043du044bu043c technique the house.method includes a process of coating a metal powder mixture by u0442u0435u0440u043cu043eu0434u0438u0444u0444u0443u0437u0438u043eu043du043du043eu0433u043e saturation a fraction of the structure products in which the products are left in the container simultaneously with the u043du0430u0441u044bu0449u0430u044eu0449u0435u0439 powder mixture of metal powder (based on zinc or u0445u0440u043e ma with a zinc oxide and possible additives, other packing materialfor example, titanium dioxide, aluminium oxide).the u0442u0435u0440u043cu043eu0434u0438u0444u0444u0443u0437u0438u043eu043du043du043eu0433u043e saturation comprises four successive phases in the following order: the phase of a collapsing dust cloud over four and from metallic powder filling the entire volume of the process container, in which the particles are deposited on the surface of the metal powder evenly through the u0442u0440u0438u0431u043e products the static effectand the maximum length of this phase is not more than 15 min at a speed of rotation of the container at least 7 rpm (time phase can be reduced greatly, the eu whether to increase the speed of the container in two times).then starts the heating phase to the preset temperature in the range from 250 to 500u00b0u0441 with heating rate, 5u00b0C / min, when the speed of rotation of the container, not less than 5 on the / min and the duration of this phase is not less than 50 minutes. then the phase equilibrium at the temperature when the speed of rotation of the container at least 2 to 3 rpm, 5 min).such a rotation is u0433u043eu043cu043eu0433u0435u043du043du043eu0435 distribution of temperature of the entire area is processed in detail. and then a phase of
