METHOD FOR THERMOCHEMICAL TREATMENT OF TOOL Russian patent published in 1995 - IPC

Abstract SU 1605572 A1

FIELD: metallurgy. SUBSTANCE: method involves applying titanium nitride at 10^-1-10^° Pa and nitriding at pressure not below 6.65 Pa. Nitriding and application of titanium nitride are effectuated in one reaction volume. Method allows two technological processes (nitriding and application of titanium nitride) to be conducted in one technological cycle and in one unit. EFFECT: increased efficiency of method and increased operational strength of treated tool (by 35-40%) as compared with known method. 3 dwg, 1 tbl
