(54) СПОСОБ НАНЕСЕНИЯ ОБМАЗКИ(54) METHOD OF APPLICATION
tt
Изобретение относитс к химико мической обработке металлов и сплавов, а именно к процессам термо-диффуэионвого насыщени из обмазок, и может быть использовано при проведении химико-термической обработки в обмазках.The invention relates to the chemical treatment of metals and alloys, in particular, to the processes of thermal diffu- sion saturation from washings, and can be used when carrying out chemical and thermal treatment in washings.
Известен способ нанесени обмазки на издели , заключающийс в том, что просе нные через сито 02О порошки тщательно перемешивают, развод т св зкой до сметанообразной консистенции. Полученную пасту нанос т на обезжиренную поверхность издели методом окунани или кистью и затем просушивают f 1J.There is a known method of applying a coating on the products, in which the powders sifted through a sieve 02O are thoroughly mixed, diluted with a binder to a creamy consistency. The resulting paste is applied to the degreased surface of the product by dipping or brushing and then drying f 1J.
Применение известного способа позвол ет совмещать химико-термическую обработку с закалкой, однако операци нанесени обмазки окунанием или кистью вл етс трудоемкой, так как использо- вание известного способа предусматривает многократное, послойное нанесение активной пасты на деталь дл создани сло обмазки толщиной 3-5 мм.The application of the known method makes it possible to combine chemical-heat treatment with quenching, but the operation of applying a dipping by dipping or brushing is laborious, since the use of the known method involves the repeated, layer-by-layer application of an active paste to a part to create a 3-5 mm thick layer of coating.
Цель изобретени - снижение трудоемкости нанесени обмазки.The purpose of the invention is to reduce the labor intensity of the coating.
Поставленна цель достигаетс тем, что деталь помещают во временную форьму , затем пространство между деталью и формой заполн ют активной пастой и просушивают.The goal is achieved by placing the part in a temporary shape, then the space between the part and the form is filled with the active paste and dried.
Зазор между деталью и стенкой формы составл ет 4-6 мм.The gap between the part and the wall of the mold is 4-6 mm.
Временную форму изготовл ют из бумаги , ткани и другого материала. Сушку обмазки производ т вместе с формой при 8О-1ОО С 1 ч. Химико-термическую обработку осуществл ют обычным способом Временна форма сгорает при помещении детали в печь.The temporary form is made of paper, cloth and other material. Drying of the coating is carried out together with the mold at 8O-1OO. With 1 hour. Chemical-thermal treatment is carried out in the usual way. The temporary form burns out when the part is placed in the furnace.
Пример 1. Изготавливают временную бумажную форму (с размерами, превышающими размеры детали на толщину сло обмазки, например на 5 мм). На дно формы заливают активную пасту, например борирующуто, слоем 5 мм, просушивают при комнатной температуре, на полученную подложку помещают обезжиренную деталь, вс поверхность которой должна быть обработана. Затем пространство между деталью и формой также за. ливают активной пастой. Толщина обмазки над верхней поверхностью детали 3-5 мм. Сушка проадводитс вместе с формой при 8О-10О С 1 ч. Дл ускорени сушки в форме делают надрезы или проколы, облегчающие удаление летучих компонентов св зки. Example 1. Make a temporary paper form (with dimensions greater than the dimensions of the part on the thickness of the layer of coating, for example, 5 mm). At the bottom of the mold, an active paste is poured, for example, boring, with a layer of 5 mm, dried at room temperature, a degreased part is placed on the resulting substrate, the entire surface of which must be processed. Then the space between the part and the form is also behind. pour active pasta. The thickness of the coating over the top surface of the part is 3-5 mm. Drying is done along with the mold at 8 ° -10 ° C for 1 hour. In order to accelerate the drying, cuts or punctures are made in the mold to facilitate the removal of the volatile components of the binder.
Пример 2. Изготавливают временную форму с размерами, позвол ющими поместить в нее несколько деталей (рассто ние между детал ми 7-10 мм). Последующие операции производ тс ана- логично примеру 1..Example 2. A temporary shape is made with dimensions that allow it to fit several parts into it (the distance between parts is 7-10 mm). Subsequent operations are performed similarly to example 1 ..
.Пример 3. Дл обработки боковой наружной поверхности деталей изготавливают временную форму по контуру детали с зазором 4-6 мм. В этом случае нанесение обмазки с использованием временной формы, производитс без предварительного создани твердой подложки. Нерабочие поверхности издели выполн ю С: припуском под механическую обработкуExample 3. To process the lateral outer surface of the parts, a temporary shape is made along the contour of the part with a gap of 4-6 mm. In this case, the application of the coating using a temporary form is carried out without first creating a solid substrate. Non-working surfaces of the product are made with: allowance for machining
Пример 4. Дл обработки часто встречающихс в практике внутренних поверхностей различных отверстий изготавливают временную бумажную форму, которую помещают внутри рабочей поверхнос ти с зазором 5 Мм, затем пространстщэExample 4. For the treatment of frequently encountered in the practice of the internal surfaces of various openings, a temporary paper form is made, which is placed inside the working surface with a gap of 5 Mm, then spaced
между деталью и формой залипают актимной пастой и просушивают.between detail and form stick stitched with an actime paste and dried.
Использование предлагаемого способа позвол ет по сравнению с известным значительно упростить операцию нанесени обмазки, дл осуществлени которой не требуетс высока квалификаци работника . При этом, трудоемкость снижаетс в 1О-20 раз в зависимости от габаритов и формы деталей. Кроме того, гарантируетс равномерность и сплошность обмазки.The use of the proposed method allows, in comparison with the known method, to significantly simplify the coating operation, for which the high qualification of the worker is not required. At the same time, the labor intensity decreases by 1–20 times, depending on the size and shape of the parts. In addition, the uniformity and continuity of the coating is guaranteed.
