Изобретение относитс  к области металлокерамических материалов на основе меди, которые могут быть применены дл  электроэрозионной обработки сложных поверхностей с резкими перегибами и углублени ми при высокой точности обработки, например ручьев штампов дл  точной штамповки при точности профил  0,05-0,1 мм, а также при электроэрозионной прошивке пазов сложного профил  с точпостыо 0,02-0,06 мм.The invention relates to the field of metal-ceramic materials based on copper, which can be used for electrical discharge machining of complex surfaces with sharp bends and grooves with high precision machining, for example, streams of punches for precise forming with a profile accuracy of 0.05-0.1 mm, as well as with the electro-erosion firmware of the grooves of a complex profile with a point of 0.02-0.06 mm.

Известен металлокердмический материал на основе меди, содержащий 2-10% титана и 5-157о графита.A metal-coremic copper-based material containing 2-10% titanium and 5-157о graphite is known.

С пелыо повышени  пластичности и уменьшени  усадки материала предлагаетс  металлокерамический материал на основе меди, который отличаетс  от известного тем, что его компоненты вз ты в следующем соотношении, вес. %:From the pellion of increasing plasticity and reducing the shrinkage of the material, a metal-ceramic material based on copper is proposed, which differs from the well-known one in that its components are taken in the following ratio, weight. %:

Титан2-8Titanium2-8

Предлагаемый материал изготавливают путем перемешивани  порошков меди, титана и графита в смесителе в течение 6-8 час и прессовани  в прессформе под давлением 4 т/см.The proposed material is made by mixing powders of copper, titanium and graphite in a mixer for 6-8 hours and pressing in a mold under a pressure of 4 tons / cm.

Спрессованные заготовки сушат в вакууме мм рт. ст. при 200°С в течение 2 час, а затем спекают в электропечи в муфеле с засыпкой глиноземом в нейтральной или защит2Compressed blanks are dried in vacuum mm RT. Art. at 200 ° C for 2 hours, and then sintered in an electric furnace in a muffle filled with alumina in neutral or protection2

ной атмосфере при950°С в течение 2 час. Охлаждение производ т вместе с печью. Калибровку изделий после спекани  провод т под давлением 5 т/см.Noah atmosphere at 950 ° C for 2 hours. Cooling is carried out with the furnace. After sintering, product calibration is performed under a pressure of 5 t / cm.

Полученный данным способом металлокерампческий материал имеет следуюн1,ие физикомеханические свойства:The metal-ceramic material obtained by this method has the following physicomechanical properties:
