Description
(54) ПАСТА ДЛЯ ПРИТИРКИ СТАЛЬНЫХ ПОВЕРХНОСТЕЙ(54) PASTE FOR MAKING STEEL SURFACES
В табл. приведены примеры рецептур предлагаемой пасты.In tab. Examples of the formulations of the pasta are given.
Усиление поверхностного диспергировани под действием притирочной пасты, содержащей водный раствор нитрита натри достигнуто за счет образовани в процессе притирки менее прочных окисных пленок, чем оксидно-сульфидные пленки, образующиес под действием компонентов пасты в отсутствии водного раствора нитрита натри .Enhancement of the surface dispersion under the action of a lapping paste containing an aqueous solution of sodium nitrite is achieved by forming less durable oxide films in the process of lapping than oxide-sulfide films formed by the action of the components of the paste in the absence of an aqueous solution of sodium nitrite.
Данные испытаний (см. табл. 2), проведенных на машине трени ми МИ по схеме ролик-ролик nf« качении с 10%-ным проскальзьшанием (нагрузка 10 кН/м, линейна скорость верхнего образца 0,472 м/с, нижнего - 0,524 м/с с образцами из стали 40Х HRC 48-50), показали, что съем металла и шероховатость в поперечном направлении существенно зависит от количества в составеThe test data (see Table 2) carried out on the machine by firing of the MI according to the roller-roller nf "rolling pattern with 10% slip (load 10 kN / m, linear velocity of the upper sample 0.472 m / s, lower speed - 0.524 m / s with samples of steel 40X HRC 48-50), showed that removal of metal and roughness in the transverse direction essentially depends on the amount in the composition
пасты 40-50%-ного водного раствора нитрита натри .paste 40-50% aqueous solution of sodium nitrite.
Как видно из табл. 2, (хттимальна добавка водного раствора нитрита натри 8-10 вес.%, при этом обеспечиваетс увеличение съема металла,а шероховатость практически не мен етс . Поскольку концентраци нитрита натри в водном растворе составл ет 40-50%, предлагаема притирочна паста не вызьшает коррозии деталей и оборудовани .As can be seen from the table. 2, (an optimal addition of an aqueous solution of sodium nitrite is 8-10% by weight, while increasing the removal of metal, and the roughness remains almost unchanged. Since the concentration of sodium nitrite in an aqueous solution is 40-50%, the proposed paste does not corrode parts and equipment.
