    (54) METHOD FOR OBTAINING BIMETALS
    The invention relates to the technology of semi-pupils of multilayer metals, more specifically to the technology of producing bimetals from materials based on alumina and based on iron. A known method of producing bimetals, including the preparation of the contact surfaces of the joined layers of steel and aluminum, the joining of the walls by pressing with a simultaneous load i. The T-unit of the known method consists in the insufficiently high quality of the compound and the high cost of the production process. The purpose of the proposed method is to eliminate the disadvantages of the known. This goal is achieved by the fact that before pressing between the surfaces of the joined layers are placed from the silicon particles, and the heating is carried out up to 500-650 ° C; A layer of steel is coated with a film of a metal selected from the series: chromium, nil, before being applied to silicon. kel, silver, gold, tungsten, molybdenum, vanadium. Silicon particles are embedded in one of the joined layers. Before bonding, the silica particles are dispersed at a temperature of 500 s in volatile organic matter. Heating to 500-650 ° C is carried out at a rate of 20 sec / min. Pressing during heating is carried out with a force of .2-20 MPa. Heating of the layers is carried out separately. In the hot condition at a temperature of 500 .. .650C, pressing is carried out at a speed of 2 ... 20 MPa / min. After pressing, the bimetal is cooled to 20 s / min, then kept at this temperature for one hour, then cooled to ambient temperature. Oxidation is performed under load. The drawing shows the aluminum-silicon-steel compound under the conditions of pressing and heating. The means 1 are used to create pressure, the press-inductor 2 serves as a heater, the part 3 is made of coated steel 4, the seam 5 has a triangular cross section, b is silicon particles, 7 is a part made of aluminum.
    The following table lists examples, illustrating the invention.
    These results were obtained during tensile tests of samples, during which the tensile strength of the compound and the tensile strength of 1050 aluminum were compared. In the compound prior to its pretreatment, and this compound that was heat treated for one hour in order to cause aging occurring when using the compound in thermoWELDING
    The results were also obtained as a result of plate bending tests on a right angle of 4 mm radius (moreover, the plate thickness was 4 mm), thermally treated and not processed, and from which they were determined

    All these examples do not limit the method and concern compounds formed on the one hand with parts made of aluminum grade 1050, and on the other hand, parts made of stainless steel type Z10CN 18-09 (example 1) and 1008 according to SAF standards (other examples) that corresponds to carbon steel containing less than 0.1% carbon.
    The results of the experiments show that the obtained compounds withstand the loads corresponding to the resistance of the rupture of the aluminum part, and in many cases the rupture does not occur at the junction, but in the gshyumin part itself - moreover, examples 3, 4 and 5 show that It is possible to bend the plate at an angle of 90 ° without damage at the point of contact of the parts.
