Изобретение относитс  к области порошковой металлургии, в частности к области металлокерамических материалов - тверды.к сплавов.The invention relates to the field of powder metallurgy, in particular to the field of metal-ceramic materials - hard alloys.

Известен способ повышени  износостойкости металлокерамических твердых сплавов путем их борировани .There is a method of increasing the wear resistance of metal-ceramic hard alloys by boroning them.

Предлагаемый способ отличаетс  от известного тем, что с целью повышени  износостойкости спеченные твердые сплавы подвергают азотированию на глубину до 1 мм.The proposed method differs from that in that, in order to improve wear resistance, sintered hard alloys are subjected to nitriding to a depth of 1 mm.

Этот способ осуществл ют следующим образом .This method is carried out as follows.

Издели  из твердого сплава подвергают азотированию в среде диссоциированного аммиака при 480 650°С. Выдержка в зависимости от требуемой глубины азотировани  составл ет 30-45 час. Степень диссоциации аммиака 15-70%; толщина азотированного сло  до 1 мм.Products made of hard metal are subjected to nitriding in dissociated ammonia at 480 650 ° C. The shutter speed depending on the desired nitriding depth is 30-45 hours. The degree of dissociation of ammonia is 15-70%; thickness of the nitrated layer up to 1 mm.

Промышленные испытани  резцов, изготовленных нз твердого сплава Т5К10 и подвергнутых азотированию, показывают, что стойкость азотированных резцов на операции отрезки колец нодшинпнков возрастает в 2-2,5 раза но сравнению с фактической стойкостью неазотированных резцов.Industrial tests of incisors made of hard alloy T5K10 and subjected to nitriding show that the nitrided cutters durability at the operation of cutting pieces of nodshinpinks increases 2-2.5 times compared with the actual durability of non-nitrated cutters.

Сравнительные испытани  резцов из твердого снлава Т5К10, нодвергиутых азотированию н борировапню, показывают, что износ азотированных резцов по задней грани при обработке стали ШХ-15 на 35-40% меньще, чем износ борированных резцов.Comparative tests of hard-toothed incisor T5K10 incisors with borirovapnyu show that the wear of nitrided incisors on the back face when machining ShH-15 steel is 35-40% less than the wear of borin incisors.

Предмет изобретени Subject invention

Способ химико-термической обработки металлокерамических твердых сплавов, отличающийс  тем, что, с целью повышени  износостойкости , спеченные твердые сплавы подвергают азотированию на глубину до 1 мм.The method of chemical-heat treatment of metal-ceramic hard alloys, characterized in that, in order to increase wear resistance, sintered hard alloys are subjected to nitriding to a depth of 1 mm.
