Изобретение относитс  к области химикотермической обработки металлов, а именно к процессам металлизации изделий в вакууме.The invention relates to the field of chemical heat treatment of metals, namely, the processes of metallization of products in vacuum.

Известен способ вакуумной металлизации при автономном нагреве металлизатора и обрабатываемых изделий. Температура нагрева изделий 200-700°С. Максимальное рассто ние между обрабатываемым изделием и металлизатором не превышает 50 мм.There is a method of vacuum metallization with autonomous heating of the metallizer and processed products. The heating temperature of products is 200-700 ° C. The maximum distance between the workpiece and the metallizer does not exceed 50 mm.

Предлагаемый способ отличаетс  от известного тем, что с целью получени  бериллиевых покрытий на издели х, удаленных от металлизатора на значительное рассто ние (до 400 мм), обработку осуществл ют при непрерывном пропускании инертного газа от металлизатора к изделию.The proposed method differs from the known one in that in order to obtain beryllium coatings on products remote from the metallizer for a considerable distance (up to 400 mm), the treatment is carried out by continuously passing an inert gas from the metallizer to the product.

Способ иллюстрируетс  чертежом.The method is illustrated in the drawing.

Издели  1 нагревают в вакуумной камере, сообщающейс  с контейнером 2, в котором находитс  металлизатор (порошок берилли ) 3. От порошковой смеси к издели м непрерывно пропускают инертный газ 4, например гелий. Температуру изделий поддерживают не ниже 300°С, температура металлизатора 900- 1100°С.The articles 1 are heated in a vacuum chamber in communication with the container 2, in which there is a metallizer (beryllium powder) 3. An inert gas 4, for example helium, is continuously passed from the powder mixture to the product m. The temperature of the products is supported not below 300 ° C, the temperature of the metallizer is 900-1100 ° C.

Пример 1. Бериллизацию изделий из стали 25X1МФ провод т при температуре изделий 400-600°С. Порошок берилли  нагревают В вакууме 6 10Example 1. The beryllization of articles made of steel 25X1MF is carried out at a product temperature of 400-600 ° C. The beryllium powder is heated in vacuum 6 10

рт. ст. до 1100°С.Hg Art. up to 1100 ° C.

Затем над порошковой смесью по направлению к издели м пропускают гелий при снижении вакуума до 8 10 мм рт. ст.Then, above the powder mixture, helium is passed in towards the product while reducing the vacuum to 8–10 mm Hg. Art.

В течение 15 час на издели х с температурой 550°С, расположенных от металлизатора на рассто нии 400 мм, формируетс  плотное бериллиевое покрытие.Within 15 hours, a dense beryllium coating is formed on products with a temperature of 550 ° C located from the metallizer at a distance of 400 mm.

Пример 2. Бериллизацню изделий из алюмини  АД1 провод т при температуре изделий 400°С. Порошок берилли  нагревают в вакууме 8 10 мм рт. ст. до 1050°С. Затем над порошковой смесью берилли  пропускают по направлению к издели м гелий при снижении вакуума до И)- мм рт. ст. При этом происходит отложенне не детал х плотного сло  берилли .Example 2. Beryllisate of aluminum products AD1 is carried out at a product temperature of 400 ° C. The beryllium powder is heated in a vacuum of 8 to 10 mm Hg. Art. up to 1050 ° C. Then, over the powder mixture, beryllium is passed towards the product m helium while reducing the vacuum to I) - mm Hg. Art. When this happens, the delayed part of the dense layer of beryllium does not occur.
