Beschreibung
Zusammenfassung:	FIELD: process engineering.SUBSTANCE: invention relates to metallurgy, mainly, to modification of parts made of hard alloys used for cold and hot metal and metal alloy forming, for example, cutting. This drill has wear-proof surface ply produced by thermal processing and consisting of cobalt compounds with hydrogen and oxygen. Said wear-proof surface ply can be recovered many times at drill regrinding.EFFECT: higher wear resistance.4 ex Изобретение относится к области металлургии и горного дела, преимущественно к способам модификации изделий из твердых сплавов, применяемых в горном деле и при холодной и горячей механической обработке металлов и металлических сплавов, например, резанием. Сверло имеет износостойкий приповерхностный слой, полученный термообработкой и состоящий из соединений кобальта с водородом и кислородом. Обеспечивается возможность многократного создания износостойкого приповерхностного слоя при переточке сверла. Увеличивается износостойкость сверла. 4 пр.
