Claims (15)

1. Способ модифицирования плоской металлической поверхности (1) путем наложения на указанную поверхность перфорированного листа (3) другого металла (4), причем указанный перфорированный лист (3) закрепляют на поверхности (1) матричной штамповкой, отличающийся тем, что изготавливают перфорированный лист таким образом, что каждое перфорированное отверстие (6) имеет кромку (5) и край (7) кромки, накладывают изготовленный таким образом лист на поверхность (1) так, чтобы кромки (5) перфорированных отверстий (6) образовали выступы в направлении указанной поверхности, припрессовывают путем матричной штамповки изготовленный таким образом лист к поверхности, при этом выпрямление кромок (5) и краев (7) кромок, которое сопровождается выпрессовыванием материала поверхности в перфорированное отверстие, обеспечивает надежное закрепление листа (3) на поверхности (1).1. A method of modifying a flat metal surface (1) by applying another metal (4) onto the specified surface of the perforated sheet (3), said perforated sheet (3) being fixed to the surface (1) by die-stamping, characterized in that the perforated sheet is made so in such a way that each perforated hole (6) has an edge (5) and an edge (7) of the edge, the sheet thus produced is superimposed on the surface (1) so that the edges (5) of the perforated holes (6) form protrusions in the direction of said surface, pressed by matrix stamping thus produced sheet to the surface, while the straightening of the edges (5) and the edges (7) of the edges, which is accompanied by extrusion of the surface material into the perforated hole, ensures reliable fastening of the sheet (3) on the surface (1). 2. Способ по п.1, отличающийся тем, что при формовании перфорированного листа кромки отгибают так, что они образуют угол (А) с плоскостью (D) листа, при этом их края (7) перпендикулярны плоскости (D) листа (3). 2. The method according to claim 1, characterized in that when forming the perforated sheet, the edges are folded so that they form an angle (A) with the plane (D) of the sheet, while their edges (7) are perpendicular to the plane (D) of the sheet (3) . 3. Способ по п.2, отличающийся тем, что при припрессовывании матричной штамповкой края кромок при выпрямлении оказываются скошенными под углом (А) к перпендикуляру к плоскости (D) листа, образуя тем самым в комбинации с материалом (2) поверхности (1) надежное сцепление (8) в форме ласточкина хвоста. 3. The method according to claim 2, characterized in that when pressing the matrix stamping, the edges of the edges during straightening are beveled at an angle (A) to the perpendicular to the plane (D) of the sheet, thereby forming, in combination with the material (2), the surface (1) reliable grip (8) in the form of a dovetail. 4. Способ по пп. 1-3, отличающийся тем, что лист (3) изготавливают из более прочного металла, чем металл поверхности (1). 4. The method according to PP. 1-3, characterized in that the sheet (3) is made of a more durable metal than the metal surface (1). 5. Способ по пп.1-4, отличающийся тем, что относительно мягкий металл (2) поверхности выбирают из группы, включающей алюминий, медь, олово, свинец и сплав одного или более из этих металлов. 5. The method according to claims 1 to 4, characterized in that the relatively soft metal (2) of the surface is selected from the group comprising aluminum, copper, tin, lead and an alloy of one or more of these metals. 6. Способ по пп. 1-5, отличающийся тем, что лист (3) изготавливают из железосодержащего металла или сплава, имеющего магнитные свойства. 6. The method according to PP. 1-5, characterized in that the sheet (3) is made of an iron-containing metal or alloy having magnetic properties. 7. Способ по п.6, отличающийся тем, что лист изготавливают из нержавеющей стали. 7. The method according to claim 6, characterized in that the sheet is made of stainless steel. 8. Способ по пп. 1-7, отличающийся тем, что матричную штамповку осуществляют путем штамповки. 8. The method according to PP. 1-7, characterized in that the matrix stamping is carried out by stamping. 9. Способ по пп. 1-7, отличающийся тем, что матричную штамповку осуществляют путем прокатки. 9. The method according to PP. 1-7, characterized in that the matrix stamping is carried out by rolling. 10. Изделие, изготовленное из пластины (1) относительно мягкого металла (2), имеющего на одной из своих сторон лист (3) из более прочного металла, чем металл пластины (1), отличающееся тем, что лист закреплен на пластине (1) способом по пп.1-9. 10. A product made of a plate (1) of relatively soft metal (2) having on one of its sides a sheet (3) of a stronger metal than the metal of the plate (1), characterized in that the sheet is fixed to the plate (1) the method according to claims 1 to 9. 11. Изделие по п.10, отличающееся тем, что оно представляет собой посуду для приготовления пищи (9, 10). 11. The product according to claim 10, characterized in that it is a dish for cooking (9, 10). 12. Изделие по п.11, отличающееся тем, что перфорированный лист наложен и закреплен на внешней поверхности дна (11) посуды (9). 12. The product according to claim 11, characterized in that the perforated sheet is superimposed and fixed on the outer surface of the bottom (11) of the dishes (9). 13. Изделие по п. 12, отличающееся тем, что оно изготовлено протяжкой алюминиевой пластины и способно нагреваться индукционными токами, при этом лист изготовлен из ферритной нержавеющей стали. 13. The product according to p. 12, characterized in that it is made by broaching an aluminum plate and can be heated by induction currents, while the sheet is made of ferritic stainless steel. 14. Изделие по п.11, отличающееся тем, что перфорированный лист наложен и закреплен на внутренней поверхности дна (12) посуды (10). 14. The product according to claim 11, characterized in that the perforated sheet is superimposed and fixed on the inner surface of the bottom (12) of the dishes (10). 15. Изделие по п.14, отличающееся тем, что лист и поверхность (1) покрыты антипригарным покрытием (13). 15.
