METHOD FOR TREATMENT OF HARD-ALLOY CUTTING TOOLS Russian patent published in 1998 - IPC

Abstract RU 2119551 C1

FIELD: ion-beam processes for production of materials with preset properties, in particular, methods of increasing wear resistance of hard-alloy cutting tools. SUBSTANCE: method includes successively treatment of the surface of hard-alloy cutting tool with titanium ions with energy of 25-35 keV and dose of 2•10¹⁷-5•10¹⁷ ion/sq.cm and pulse irradiation with powerful ion beam of carbon and hydrogen with energy of 300 keV, current density of 50-150 A/sq. cm and ion dose of 10¹⁴ ion/sq.cm. Mixing of implanted ions is due to effect of high-power ion beam to form carbide and oxide phases of TiC, tiO₂ and types and their penetration to depth of 200 . EFFECT: higher efficiency. 2 dwg
