Abstract
Description
Изобретение относится к машиностроению, в частности к созданию антифрикционных покрытий для узлов трения и деталей крепежа, в том числе гаек малых размеров, выполненных из нержавеющих сталей и никелевых сплавов и работающих при температуре до 500оС.The invention relates to mechanical engineering, in particular to creation of antifriction coatings for friction components and fasteners, including screws of small size, made of stainless steels and nickel alloys, and operating at temperatures up to 500 C.
Цель изобретения - обеспечение многократного свинчивания резьбовых деталей после нагрева при 500оС, повышение вибрационной прочности покрытий и выход годных изделий, а также создание пожаробезопасных условий работы.The purpose of the invention - providing multiple screwing the threaded parts after heating at 500 ° C, increased vibration strength of coatings and yield ratio, and also the creation of fireproof operating conditions.
При получении суспензии используют фритту, кремнийорганическую гидрофобизующую добавку в виде эмульсии, оксиэтилированный алкилфенол и в качестве дисперсионной среды - воду. In preparing the suspension, a frit, an organosilicon hydrophobic additive in the form of an emulsion, hydroxyethylated alkyl phenol, and water are used as a dispersion medium.
Кремнийорганическая гидрофобизующая добавка (КГ) состоит из полиметилсилоксанового олигомера (ПМСО) по ТУ 6-02-909-79 и ингибитора термоокисления (ИГ) по ТУ 38.401476-84 в соотношении 1:0,7. The organosilicon hydrophobizing additive (KG) consists of a polymethylsiloxane oligomer (PMSO) according to TU 6-02-909-79 and a thermal oxidation inhibitor (IG) according to TU 38.401476-84 in a ratio of 1: 0.7.
Суспензию готовят следующим образом. Отвешивают необходимые количества фритты и графита, смешивают их и перетирают. К перетертой смеси добавляют необходимое количество гидрофобизующей добавки в виде 70%-ной водной эмульсии К21ИТ и общую смесь размешивают и вновь перетирают. К полученной смеси добавляют требуемое количество воды, в которой заранее растворяют оксиэтилированный алкилфенол (неонол). Раствор неонола вливают при перемешивании. The suspension is prepared as follows. Weigh the necessary quantities of frits and graphite, mix them and grind. The required amount of water-repellent additive in the form of a 70% aqueous K21IT emulsion is added to the grinded mixture, and the total mixture is stirred and ground again. The required amount of water is added to the resulting mixture, in which hydroxyethylated alkyl phenol (neonol) is dissolved in advance. The neonol solution is poured with stirring.
Нанесение покрытия осуществляется на предварительно обезжиренные промытые и просушенные детали, например болт, шайбу и гайку, в том числе на внутреннюю поверхность отверстий малых диаметров путем окунания на 20-30 c с последующей сушкой на воздухе в течение 20-30 мин и отжигом при 560 ± 10оС продолжительностью 5-8 мин.Coating is carried out on previously defatted washed and dried parts, for example, a bolt, washer and nut, including on the inner surface of small diameter holes by dipping for 20-30 s followed by drying in air for 20-30 minutes and annealing at 560 ± 10 about With a duration of 5-8 minutes
Конкретные примеры составов суспензий и фритт приведены в табл.1. Specific examples of the compositions of suspensions and frits are given in table 1.
При оценке свойств суспензий определяют коэффициент трения резьбовых пар из стали ЭИ961 с нанесенным покрытием после нагрева узла в сборе при 500оС в течение 100 ч, усилии затяжки 930 кгс и после определенного числа свинчиваний, а также коэффициент трения и выход годных деталей для гаек малого диаметра 6 мм. Вибропрочность покрытия определяют на вибростенде ВЭДС-200А при симметричном цикле нагружения в резонансном режиме при постоянном напряжении в рабочем сечении 50 кгс/мм на листовых образцах стали ЭИ 962 по наличию скола покрытия при разрушении образцов.When evaluating suspensions properties determined coefficient threaded pairs of friction of steel EI961 coated after heating unit assembly at 500 ° C for 100 hours, 930 kgf tightening force, and after a number of make-ups, as well as the friction coefficient and the yield ratio of components for small nuts diameter of 6 mm. The vibration resistance of the coating is determined on a VEDS-200A vibration stand with a symmetric loading cycle in the resonant mode at a constant voltage in the working section of 50 kgf / mm on sheet samples of steel EI 962 by the presence of a cleavage of the coating during destruction of the samples.
Результаты испытаний приведены в табл.2. The test results are shown in table.2.
Описываемый состав повышает ресурс нагрева резьбовых пар при 500оС, обеспечивает возможность покрытия суспензией гаек малого диаметра и способствует проведению технологического процесса в пожаробезопасных условиях.The described composition increases threaded resource steam heating at 500 ° C, allows the coating suspension small diameter nuts and promotes technological process in fireproof conditions.
