Description
Изобретение относитс к способам улучшени поверхностных свойств изделий из черных металлов методами химической и термической обработки .The invention relates to methods for improving the surface properties of ferrous metal products by chemical and thermal processing methods.
При цементировании стальных изделий в твердом карбюризаторе с применением нагрева токами высокой частоты иногда имеет место плавление науглерожеиной поверхности в точках контакта с частицами твердого карбюризатора, что приводит к браку цементируемых изделий.When cementing steel products in a solid carburizer using high-frequency heating, sometimes there is melting on a carbon-free surface at points of contact with solid carburizer particles, which leads to marriage of the cemented products.
Описываемый способ цементации стали в твердом карбюризаторе с применением нагрева до 950-1150° токами высокой частоты или иными способами, устран ет брак, причиной которого вл етс местное оплавление поверхности изделий. Достигаетс это путем предварительного нанесени на подлежащую цементации деталь тонкого сло мела, изолирующего се от непосредственного соприкосновени с частицами карбюризатора , что устран ет воз.можность оплавлени поверхности, не преп тству диффузии углерода в сталь.The described method of cementation of steel in a solid carburizer using heat applied to 950-1150 ° C by high frequency currents or by other means eliminates a defect caused by local melting of the surface of the products. This is achieved by preliminarily applying a thin layer of chalk to the part that is cemented, which isolates it from direct contact with the carburizer particles, which eliminates the possibility of surface melting without interfering with the diffusion of carbon into the steel.
Обмазку приготовл ют из мела, растертого в тонкий порошок, который смешивают с водой до получени суспепзии сметанообразной консистенции . Нанесение сло обмазки производ т однократным погружением издели с предварительно очищенной поверхностью в меловую суспензию . После этого нанесенный слой подвергают двухчасовой сушке при температуре около 20-30°. После сушки издели подвергают цементации обычными способами.The coating is prepared from chalk, ground into a fine powder, which is mixed with water until a creamy consistency is obtained. Applying a layer of coating is performed by immersing the product once with the previously cleaned surface in a chalky suspension. After that, the applied layer is subjected to a two-hour drying at a temperature of about 20-30 °. After drying, the product is cemented by conventional methods.
Удаление обмазки с поверхности подвергшегос цементации издели осуществл ют пескоструйной обработкой или кратковременным отмачиванием в воде, нагретой до 50-60°.Removing the coating from the surface of the cemented product is carried out by sandblasting or short-term soaking in water heated to 50-60 °.
Применение обмазки не сказываетс на глубине цементованного сло или продолжительности процесса цементацииПредмет изобретени The application of the coating does not affect the depth of the cemented layer or the duration of the grouting process.

частоты, отличающийс тем, что, с целью устранени оплавлени поверхности в точках контакта издели с частицами карбюризатора, изделие перед цементацией покрывают тонким слоем меловой обмазки.frequencies, characterized in that, in order to eliminate surface melting at the points of contact of the product with carburizer particles, the product is coated with a thin layer of chalky coating before cementation.
