Description

Удаление остаточного обезуглероженного сло  с поверхности стальных изделий повторным шлифованием  вл етс  трудоемким процессом, а в случа х деталей малых размеров, или имеющих сложнопрофилчрованные поверхности - неприемлимым.Removing the residual decarburized layer from the surface of steel products by repeated grinding is a laborious process, and in the case of parts of small dimensions or with complexly shaped surfaces it is unacceptable.

Предлагаемый способ удалени  остаточного обезуглероженного сло  позвол ет значительно упростить процесс, повысить его производительность и снизить трудоемкость удалени  обезуглероженного сло  с поверхности изделий.The proposed method for removing residual decarburized layer makes it possible to significantly simplify the process, increase its productivity and reduce the laboriousness of removing the decarburized layer from the surface of the products.

Сущность предлагаемого способа состоит в том, что поверхность издели  окисл ют, подверга  его анодному оксидированию на глубину обезуглероженного сло .The essence of the proposed method is that the surface of the product is oxidized, exposing it to anodic oxidation to the depth of the decarbonized layer.

Затем оксидный слой удал ют известными способами, при этом точно выдерживаютс  нужные размеры деталей.Then, the oxide layer is removed by known methods, while maintaining the required dimensions of the parts.

В том же случае, когда необходимо обеспечить защитное или декоративное покрытие детали, полученный оксидный слой не снимаетс  I-, тогда имеет место совмещение технологических операций разрушенил остатков обезуглероженного сло  с созданием пассивирующей окисной пленки.In the same case, when it is necessary to provide a protective or decorative coating for the part, the resulting oxide layer is not peeled off I-, then a combination of technological operations destroys the remains of the decarburized layer with the creation of a passivating oxide film.

Claims (2)

1.Способ удалени  остаточного обезуглероженного сло  с поверх ности щлифованных стальных изделий, отличающийс  тем, что, с целью снижени  трудоемкости, слой обезуглероженного металла окисл ют , дл  чего обрабатываемые издели  подвергают анодному оксиди рованию на глубину, равную толщине обезуглероженного сло , после чего оксидный слой удал ют известными способами1. A method for removing residual decarburized layer from the surface of ground steel products, characterized in that, in order to reduce labor intensity, the layer of decarburized metal is oxidized, for which the workpieces are subjected to anodic oxidation to a depth equal to the thickness of the decarburized layer, after which the oxide layer removed by known methods 2.Способ по п. 1, отл и ч а ю щи и с  тем,, что, с изделий, подлежащих оксидированию в защитных или декоративных цел х, оксидный слой не удал ют.2. The method according to claim 1, in addition to the fact that, from the products to be oxidized for protective or decorative purposes, the oxide layer is not removed.
