Zusammenfassung:	FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy and mining, in particular, to a disposable die made from cobalt-bearing hard alloy. Said disposable die has surface layer of solid cobalt-bearing alloy, modified with cobalt hydroxide Co(OH)and heterogenites.EFFECT: higher wear resistance of die.1 cl, 2 ex Изобретение относится к области металлургии и горного дела, а именно к неперетачиваемому штампу из кобальтсодержащего твердого сплава. Упомянутый неперетачиваемый штамп имеет приповерхностный слой кобальтсодержащего твердого сплава, модифицированный гидроксидом кобальта Co(OH)и гетерогенитами. Обеспечивается увеличение износостойкости штампа. 2 пр.
