Description
Изобретение относитс к способам упрочнени поверхности стальных изделий путем обработки ее притпром с нанесением упрочн ющих веществИзвестные подобные способы, также предусматривающие использование в качестве упрочн ющего вещества дисульфид молибдена, не обеспечивают достаточно высокого качества упрочнени .The invention relates to methods for hardening the surface of steel products by treating it with preparatory and applying hardening substances. Known similar methods, also involving the use of molybdenum disulfide as a hardening substance, do not provide a sufficiently high hardening quality.
Дл устранени этого недостатка предлагаетс упрочнение производить с использованием порошкообразного дисульфида молибдена, смешанного с клеем БФ-2 и запрессованного в пазы трущейс поверхности прибора.To eliminate this drawback, it is proposed to make hardening using molybdenum disulfide powder mixed with BF-2 glue and pressed into the grooves of the rubbing surface of the device.
На фиг. 1 представлено упрочн емое изделие цилиндрической формы и притир, вид сбоку; на фиг. 2 - то же, вид спереди.FIG. 1 shows a cylindrical strengthened product and grinding, side view; in fig. 2 - the same, front view.
К вращающемус изделию / прижимаетс притир 2, снабженный пазами 3, заполненными массой из порошкообразного дисульфида молибдена и кле БФ-2. Рекомендуетс удельное давление притира 2,5- 3,5 кг/см и скорость скольжени 4,5-5,5 .«/сек. После запрессоЕКи. упрочн ющей массы в пазы притира, последний помещаетс в печь с температурой 140-150°, где выдерживаетс 2-3 часа. В результате обработки изделий по предлагаемому способу на поверхности издели образуетс диффузионный слой двусер«истого молибдена темно-серого или черного цвета. Диффузионный слой имеет толщину 2-7 мк и в дес тки раз повышает износостойкость и противозадирочные свойства поверхности обрабатываемого издели .The grinding compound 2 is pressed against the rotating product, equipped with grooves 3 filled with a mass of molybdenum disulfide powder and BF-2 glue. A specific ground pressure of 2.5-3.5 kg / cm and a slip speed of 4.5-5.5 are recommended. "/ Sec. After the press. hardening mass in the grooves of the lap, the latter is placed in a furnace with a temperature of 140-150 °, where it is kept for 2-3 hours. As a result of processing the products according to the proposed method, a diffusion layer of a dark gray or black diffuser double raw molybdenum layer is formed on the product surface. The diffusion layer has a thickness of 2-7 microns and ten times increases wear resistance and EP properties of the surface of the workpiece.
