Description
Известный способ диффузионной сварки и пайки с предварительным окислением соедин емых поверхностей не обеспечивает вьгсохой скорости диффузионных процессов.The known method of diffusion welding and soldering with the preliminary oxidation of the joining surfaces does not provide a high rate of diffusion processes.
Предлагаемый способ позвол ет интенсифицировать диффузионные процессы благодар тому, что окисление осуществл ют при температуре фазового превращени окисла свариваемого материала + 100 С.The proposed method allows to intensify diffusion processes due to the fact that the oxidation is carried out at the phase transformation temperature of the welded material oxide + 100 C.
Описываемый способ основан на свойствах окисных пленок р да металлов претерлевать фазовые превращени при нагреве. Примером могут служить окислы железа, которые при нагреве до температуры примерно 150-250 С претерпевают фазовое прев- ращение -Р.г. Р О, - Как показывают исследовани , поверхности, окисленные при температурах, близких к температуре фазового превращени окисла, обладают повышенной активностью и легче свариваютс . The described method is based on the properties of oxide films of a series of metals to undergo phase transformations during heating. An example is iron oxides, which, when heated to a temperature of about 150–250 ° C, undergo a phase transformation — Rg. RO, - As studies show, surfaces oxidized at temperatures close to the phase transformation temperature of the oxide have increased activity and are easier to weld.
Технологический процесс диффузионной сваки и пайки заключаетс в предварительном окислении соедин емых поверхностей деталей в интервале температуры фазовых превращений окислов, образующихс на металле, The technological process of diffusion bonding and brazing consists in the preliminary oxidation of the joined surfaces of parts in the temperature range of phase transformations of oxides formed on the metal,
+ 100 С и сварке деталей по обычной технологии с нагревом и давлением в любой среде (газовой, жидкой и т.д.).+ 100 C and welding parts using conventional technology with heating and pressure in any environment (gas, liquid, etc.).
Точное значение температуры, при которой необходимо вести окисление свариваемых поверхностей, и врем окислени подбираютс экспериментально. Например, температура окислени свариваемых поверхностей ста.-.и 3 (0,04%С) равна 200°С, врем окислени 30 мин.The exact value of the temperature at which it is necessary to oxidize the surfaces to be welded, and the oxidation time is selected experimentally. For example, the oxidation temperature of the welded surfaces of the stationary .- and 3 (0.04% C) is 200 ° C, the oxidation time is 30 minutes.
Как показывает проверка, прочность сварного соединени деталей из стали 3, поверхности которых были окислены при указанной температуре, оказалась намного выиге значени прочности, полученного при диффузионной сварке деталей из той же стали, у которых не производилось окисление поверхности . Режим сварки: t 850 С; Р - 2,3 кг/мм t 5 мин, нагревательна средаAs the test shows, the strength of the welded joint of parts from steel 3, whose surfaces were oxidized at the indicated temperature, proved to be much better than the value of strength obtained by diffusion welding of parts from the same steel, which did not oxidize the surface. Welding mode: t 850 С; Р - 2.3 kg / mm t 5 min, heating medium
