METHOD OF INCREASING OF A WEAR RESISTANCE OF THE CEMENTED CARBIDE TOOL OR A HARDWARE PRODUCT Russian patent published in 2005 - IPC

FIELD: treatment of the wear-resistant hardware products of the wear-resistant hardware products of an instrumental designation.

SUBSTANCE: the invention is pertaining to the field of treatment of the wear-resistant hardware products of an instrumental designation and may be used for increasing an operational life of gears and tools, components of machines and the devices working in conditions of cutting, friction and an abrasive wear-out. The technical result of the invention is an increase almost in two times of the wear resistance of the cemented-carbide tools or hardware products, predominantly made out of a tungsten-free metal-ceramic alloy based on titanium carbide and nickel-chromium compound (TiC-NiCr). The indicated technical result is obtained by conduct of the treatment of the effective areas of the tools or the hardware products with a pulsing high-current beam coupling with a pulse duration - 2-3 microseconds, power of electrons - 10-30 keV, density of power - 4.5-5.5 Joule/cm² and a number of pulses - from 10 up to 30.

EFFECT: the invention ensures an increase almost in two times of the wear resistance of the cemented-carbide tools or hardware products.
