METHOD OF TREATING CUTTING TOOL OF QUICK-CUTTING STEELS Russian patent published in 1998 - IPC

Abstract SU 1549110 A1

FIELD: plasma technology. SUBSTANCE: tungsten carbide ions with energy 40-100 keV are implanted in dose 5•1016-1017 cm-2 into wear-resistant titanium nitride coating applied on cutting tool surface resulting in increasing wear resistance of tool by a factor of 2.4-2.6. EFFECT: increased wear resistance of tools. 1 tbl
