Изобретение относитс  к области металлокерамических материалов, в частности к электроконтактным материалам, которые могут быть использованы дл  изготовлени  деталей, работающих в услови х скольз ш,его токоподвода .The invention relates to the field of metal-ceramic materials, in particular to electrocontact materials, which can be used for the manufacture of parts operating under the conditions of the slip gaps and its current supply.

Известен электроконтактный металлокерамический материал, содержащий, вес.%: Железо25-75Known electro-contact cermet material containing, wt.%: Iron25-75

МедьОстальноеCopperE rest

Предложенный материал отличаетс  от известного тем, что с целью повышени  износостойкости в его состав введен феррохром нри следующем соотношении компонентов, вес.%:The proposed material differs from the well-known fact that, in order to increase wear resistance, ferrochrome is introduced into its composition at the following ratio of components, wt.%:

МедьОстальноеCopperE rest

Предложенный материал получают следующим образом.The proposed material is obtained as follows.

Исходные порошкообразные компоненты: железо, феррохром, медь - после смешивани  прессуют при давлении 2 т/см в заготовки, которые затем спекают при 1050°С в защитной атмосфере в течение 1 час, а затем донрессовывают при давлении 8 т/см.The initial powder components: iron, ferrochrome, copper — after mixing, are pressed at a pressure of 2 t / cm into blanks, which are then sintered at 1050 ° C in a protective atmosphere for 1 hour, and then donated at a pressure of 8 t / cm.

В таблице приведены свойства предложенного материала в сравнении с известным.The table shows the properties of the proposed material in comparison with the known.
