Description
Изобретение относитс к области производства твердосплавных изделий, в частности к улучшению их прочности термообработкой с наложением ультразвука.This invention relates to the field of manufacturing carbide products, in particular, to improving their strength by heat treatment with the application of ultrasound.
Примен ема в насто щее врем термообработка спеченных изделий из твердых сплавов повышает их износостойкость, но не дает суш,ественного увеличени прочности.The currently used heat treatment of sintered hard alloy products increases their wear resistance, but does not give sushi a natural increase in strength.
Предлагаемый способ улучшени прочности изделий из твердых сплавов позвол ет на 10-ЗОо/о повысить предел их прочности при изгибе.The proposed method of improving the strength of products from hard alloys makes it possible to increase the limit of their flexural strength by 10 ° -30 ° / o.
Отличительна особенность предлагаемого способа заключаетс в том, что при термообработке твердосплавные издели в процессе отпуска подвергают ультразвуковой обработке . Это существенно повыщает их прочность.A distinctive feature of the proposed method is that during heat treatment, carbide products are subjected to ultrasonic treatment during the tempering process. This significantly increases their strength.
Например, в результате применени указанного способа обработки прочность на изгиб изделий из сплава ВК15 увеличиваетс с 219 до 281 кг/мм. Спеченные издели из этого сплава обрабатывают следующим образом: нагрев до температуры 1000-1250°С, закалка в расплавленную смесь низкоплавких солей либо в жидкую ванну легкоплавкого сплава , нагрев до температуры 250-750°С в течение 2-120 лшн и обработка одновременно ультразвуком.For example, as a result of applying this method of treatment, the bending strength of products made from BK15 alloy increases from 219 to 281 kg / mm. Sintered products from this alloy are treated as follows: heating to a temperature of 1000–1250 ° C, quenching into a molten mixture of low-melting salts or into a liquid bath of a fusible alloy, heating to a temperature of 250–750 ° C for 2–120 lsn and processing simultaneously with ultrasound.
На чертеже приведен график зависимости Прочности на изгиб сплава ВК15 в зависимости от времени обработки при 600°С образцов: закаленных и озвученных - 1 закаленных без последующего озвучивани - 2; без закалки и без озвучивани - 3; без закалки с озвучиванием - 4.The drawing shows a graph of the dependence of the Flexural strength of the BK15 alloy as a function of the processing time at 600 ° C of samples: hardened and sounded - 1 hardened without subsequent dubbing - 2; without quenching and without voicing - 3; without quenching with dubbing - 4.
Предложенный способ эффективен дл обработки спеченных изделий из твердых сплавов , содержащих 6 вес. о/ц и более кобальта.The proposed method is effective for processing sintered hard metal products containing 6 wt. o / c and more cobalt.
