Description
Примен емые способы упрочнени поверхностей трущихс или контактирующих деталей не всегда предохран ют эти поверхности от схватывани и фретинг-коррозии.The applied methods of strengthening the surfaces of the rubbing or contacting parts do not always protect these surfaces from seizure and fretting corrosion.
Описываемый способ предохр ;1ени от схватывани и фретинг-коррозии стальных поверхностей, трущихс друг о друга или наход щихс в контакте в резьбовых, шлицевых, шпоночных и т. п. соединени х, позвол ет повысить противозадирные свойства обработанных поверхностей и предотвратить их взаимное схватывание. Достигаетс это тем, что на одну или обе трущиес или контактирующие поверхности нанос т электролитическим путем покрытие из кобальта. Электролитическое осаждение кобальта можно осуществл ть известными способами, желательно из щелочного электролита. Толщина кобальтового сло составл ет 12-15 мк иа сторону.The described method of preventing the seizure and fretting of corrosion of steel surfaces rubbing against each other or in contact in threaded, splined, keyed, etc. joints prevents the anti-seize properties of the treated surfaces and prevents them from sticking together. This is achieved by the fact that a coating of cobalt is electrolytically applied to one or both of the rubbish or contacting surfaces. Electrolytic deposition of cobalt can be carried out by known methods, preferably from an alkaline electrolyte. The thickness of the cobalt layer is 12-15 µm.
Способ предназначен дл обработки контактирующих поверхностей , работающих в услови х сухого трени при небольщих скорост х MX взаимного перемещени , но больщих (до 500 кг/сл) нагрузках, а также дл поверхностей, контактирующих друг с другом под нат гом. В процессе трени и вызываемого им нагревани деталей на поверхности и в поверхностных объемах кобальтового покрыти образуютс весьма прочные неметаллические пленки окислов. Скорость процесса образовани этих пленок нревыщает скорость их разрушени , поэтому посто нное наличие пленок окислов между сопр женными поверхност ми деталей мащин значительно преп тствует образованию металлического контакта и возникновению схватывани металлов и фретингкоррозии; при этом усталостна прочность деталей повышаетс .The method is intended for the treatment of contacting surfaces operating under dry friction conditions at low speeds MX of mutual displacement, but greater (up to 500 kg / sl) loads, as well as for surfaces that are in contact with each other under tension. In the process of friction and the heating of parts caused by it, highly durable non-metallic oxide films form on the surface and in the surface volumes of the cobalt coating. The speed of the process of formation of these films increases the speed of their destruction, therefore, the constant presence of oxide films between the mating surfaces of the parts of the machine significantly prevents the formation of metal contact and the occurrence of metal hardening and fretting corrosion; while the fatigue strength of the parts increases.
Промышленна полезность пред южени подтверждаетс заключением институтов НИИтехмаш, Эксплуатации и ремонта авиационной техники ВВС и др.The industrial usefulness of southerners is confirmed by the conclusion of the institutes of NIItechmash, the operation and maintenance of aviation technology of the air force, etc.
№ 140295. - 9 Предмет изобретени № 140295. - 9 The subject invention
Способ предохранени от схватывани и фретинг-коррозии стальных новерхностей, трущихс друг о друга или наход щихс в контакте в резьбовых, шлицевых, щпоночных и т. п. соединени х, путем нанесени на них гальванических покрытий, отличающийс тем, что, с целью повыщени противозадирных свойств и надежности в работе , в качестве металла покрыти используют кобальт, слой которого толщиной, например, в 12-15 мк нанос т на одну или обе контактирующие поверхности.The method of protection from the seizure and fretting of corrosion of steel surfaces that rub together or are in contact with threaded, spline, shponochnyh, etc., by applying electroplated coatings on them, in order to increase the extreme pressure properties and reliability in operation, cobalt is used as a coating metal, a layer of which, for example, 12-15 µm thick is applied to one or both of the contacting surfaces.
