Description

Насыщение поверхности металлов серой сульфидирование - значительно снижает коэффициент трени , повышает прирабатываемость и износоустойчивость деталей, работающих на трение. ИзвестнУ химико-термические и электролитические способы сульфидировани  деталей и инструментов.The saturation of the surface of metals with sulfur sulphidation - significantly reduces the coefficient of friction, increases the workability and wear resistance of parts operating on friction. Chemical-thermal and electrolytic methods for sulfidizing parts and tools are known.

По предлагаемому способу насыщение поверхности металла серой производитс  путем электроэрозионной обработки поверхности деталей с применением электродов, изготовленных из сернистого железа.According to the proposed method, the saturation of the metal surface with sulfur is carried out by electroerosive surface treatment of parts using electrodes made of iron sulfide.

Дл  насыщени  поверхности металла серой примен етс  ручной электромагнитный вибратор или полуавтоматическа  вибрирующа  головка, которые питаютс  от электроискрового аппарата, например, типа УПР-ЗМ.To saturate the surface of the metal with sulfur, a manual electromagnetic vibrator or a semi-automatic vibrating head are used, which are powered by an electrospark apparatus, for example, of the UPR-ZM type.

Электроды изготавливаютс  из сернистого железа по следующей технологии. Железный порошок марки AM, предварительно раскисленный в атмосфере водорода при 1100-1150°, смещиваетс  в щаровой мельнице в течение 1 час с технической серой, крупностью 50 меш. Соотнощение смешиваемых материалов (в весовых процентах): железного порощка - 61 и серы - 39. После разгрузки из щаровой мельницы смесь железного порошка и серы нагреваетс  под выт жкой в открытом тигле до тех пор, пока полностью не пройдет реакци  образовани  сернистого железа. Полученное сернистое железо, представл ющее собой рыхлую массу, измельчаетс  и затем расплавл етс  в селитовой или газовой печи. Из расплавленного сернистого железа отливаютс  электроды. Заливка производитс  при 1100-1150° в тщательно высушенные земл ные формы с хорощей газопроницаемостью. После охлаждени  и очистки от пригаров электроды готовы к употреблению..The electrodes are made of iron sulfide using the following technology. The AM iron powder, previously deoxidized in an atmosphere of hydrogen at 1100-1150 °, is shifted in a balloon mill for 1 hour with a technical sulfur of 50 mesh. The mixing ratio of the materials to be mixed (in percent by weight): iron powder - 61 and sulfur - 39. After unloading from the nozzle mill, the mixture of iron powder and sulfur is heated under a hood in an open crucible until the iron sulfide reaction has completely passed. The resulting iron sulfide, which is a loose mass, is crushed and then melted in a sieve or gas furnace. Electrodes are molded from molten iron sulfide. Filling is performed at 1100-1150 ° in thoroughly dried land forms with good gas permeability. After cooling and scaling, electrodes are ready for use ..

При электроэрозионной обработке поверхности деталей с применением описанных электродов глубина насыщенного серой сло  составл ет примерно 100 мк. Стойкость волочильных матриц из стали Х12Ф,In electro-erosion surface treatment of parts using the described electrodes, the depth of the saturated gray layer is about 100 microns. Durability of drawing matrixes from steel H12F,

подвергнутых сульфидированию по описываемому способу, увеличилась в 3, 3 раза. Описанный способ достаточно прост и может найти применение при.сульфидировании р да деталей и инструментов.subjected to sulphidation according to the described method, increased by 3, 3 times. The described method is quite simple and can be used in the sulphidation of a number of parts and tools.
