FIELD: metallurgy.
SUBSTANCE: it is used waste hard-alloyed cutting product for boring tool, its wastes and cull in the capacity of high-temperature getter of protective action oxygen from oxidation of heat-treatable products, easy subject to oxidation. Getter is implemented in the form of polyhedral product in the form of block or solid polyhedr made of hard metal, containing compound made of tungsten carbide with cobalt. In comparison with well-known getter usage of hard-alloyed cutting product significantly faster (~10-50 times) protects against oxidation heat-treatable products and in major volume.
EFFECT: increasing of grade of contactless with getter protection against oxidation product.
