Предложенную композиционную электродную ленту получают прокаткой и спеканием указанных порошков.The proposed composite electrode tape is produced by rolling and sintering the above powders.
Пример. Электродную ленту изготовл ют из порошков никел в количестве 60 об. %, хрома в количестве 18 об. % и карбида титана в количестве 22 об.%.Example. The electrode tape is made of nickel powders in an amount of 60 vol. %, chromium in the amount of 18 vol. % and titanium carbide in the amount of 22 vol.%.
Процесс смешивани и плакировани составл ющих компонентов осуществл етс одновременно в автоклаве при посто нном перемешивании гидрометаллургическим способом, в результате чего на карбид титана (22 об.%) с размерами частиц 25-40 мкм наноситс 40 об.% никел , иThe process of mixing and plating the constituent components is carried out simultaneously in an autoclave with constant stirring by a hydrometallurgical method, with the result that 40% by volume of nickel is applied to titanium carbide (22% by volume) with particle sizes of 25-40 µm, and

получаетс плакирующа оболочка 10- 14 мкм, а оставшиес 20 об.% никел нанос тс на 18 об.% хрома с размерами частиц 10-30 мкм, и толщина плакирующей оболочки получаетс 10-14 мкм.a plating shell of 10-14 microns is obtained, and the remaining 20 vol% nickel is deposited on 18 vol% chromium with a particle size of 10-30 microns, and the thickness of the cladding shell is 10-14 microns.
После плакировани порошковую смесь высушивают в водородной печи при 200°С и затем прокатывают ленту шириной 40 мм и толщиной 1 мм со скоростью 2 м/мин. Прокатанную ленту спекают Б проточной водородной печи при 1300°С в течение 30 с, а затем сматывают в рулон.After plating, the powder mixture is dried in a hydrogen furnace at 200 ° C and then a ribbon 40 mm wide and 1 mm thick is rolled at a speed of 2 m / min. Laminated ribbon is sintered in a B flowing hydrogen furnace at 1300 ° C for 30 s, and then wound into a roll.
Примеры испытани на износостойкость наплавочных слоев, полученных путем наплавки предложенной композиционной электродной ленты на инструменты прокатного и волочильного производства, сведены в таблицу.Examples of the wear resistance test of the surfacing layers obtained by surfacing the proposed composite electrode tape on the tools of the rolling and drawing production are tabulated.
Из таблицы следует, что изготовление данным способом электродной ленты с твердыми включени ми дает возможность получать наплавочные покрыти с равномерным распределением твердых включений в матрице, повыша этим износостойкость покрыти , что невозможно получить известными способами.It follows from the table that the fabrication of an electrode tape with hard inclusions by this method makes it possible to obtain surfacing coatings with a uniform distribution of solid inclusions in the matrix, thereby increasing the wear resistance of the coating, which cannot be obtained by known methods.
