(54) СПОСОБ ОЧИСТКИ ДЕТАЛЕЙ ИЗ АЛЮМИНИЕВЫХ СПЛАВОВ(54) METHOD FOR CLEANING DETAILS FROM ALUMINUM ALLOYS

1one

Изобретение относитс  к термохимической очистке деталей в гидроксидных расплавах и может быть использовано, в частности дл  очистки деталей автотракторных двигателей от нагара н накипи.The invention relates to the thermochemical cleaning of parts in hydroxide melts and can be used, in particular, for cleaning parts of autotractor engines from scale and scale.

Известен способ очистки деталей, включающий обработку их в щелочном расплаве 1.A known method of cleaning parts, including processing them in an alkaline melt 1.

Обработку деталей по этому способу провод т при 450° С, Последующее охлаждение деталей в воде приводит к их короблению, а в случае очистки алюминиевьпс деталей ведет еще и к значительному растравливанию их поверхности в процессе промывки от остатков затвердевшего щелочного расплава.Processing of parts according to this method is carried out at 450 ° C. Subsequent cooling of parts in water leads to their distortion, and in the case of cleaning aluminiums, the parts also lead to significant etching of their surface during washing from residual hardened alkaline melt.

Кроме того, детали из алюминиевых сплавов , упрочн емь1х термической обработкой таких, как АЛ4, АЛ9 и др., после очистки известным способом обладают пониженными физико-механическими свойствами.In addition, parts made of aluminum alloys, hardened by heat treatment such as AL4, AL9, etc., after cleaning in a known manner, have reduced physical and mechanical properties.

Наиболее близким к предлагаемому  вл етс  способ очистки пзветиых металлов, в частности алюминиевых деталей от нагара, включающий обработку в щелочном расплаве и промьшку 2.The closest to the present invention is a method for cleaning pvetive metals, in particular aluminum parts, from carbon, including treatment in an alkaline melt and plate 2.

Детали после обработки в щелочном расплаве промьтают в воде, обрабатывают в кислотном растворе и окончательно промывают в гор чей воде.The parts after treatment in an alkaline melt are washed in water, treated in an acidic solution, and finally washed in hot water.

Однако известный способ частично снижает коробление деталей в процессе охлаждени . Растравливание же поверхности алюминиевых деталей в процессе охлаждени  н промьтки от остатков затвердевшего щелочного расплава имеет место и в этом способе, что приводит в р де случаев к браку, особенно при очистке деталей с высокой степенью чистоты поверхности, например поршней.However, the known method partially reduces the distortion of parts during the cooling process. The etching of the surface of aluminum parts in the process of cooling and rinsing from the remnants of hardened alkaline melt takes place in this method, which leads to scrap in some cases, especially when cleaning parts with a high degree of surface cleanliness, such as pistons.

Кроме того, физико-механические свойства деталей после очистки по известному спосо15 бу также снижаютс . Так, например, после очистки в щелочном расплаве с температурой 340° С твердость сплава АЛ 10В падает со Л14 до 90 ед. НВ, а сплава АЛ4 - с 90 до 42 ед. НВ.In addition, the physicomechanical properties of the parts after cleaning by a known method are also reduced. For example, after cleaning in an alkaline melt with a temperature of 340 ° C, the hardness of the alloy AL 10B drops from L14 to 90 units. HB, and alloy AL4 - from 90 to 42 units. HB
