Abstract

1,239,941. Nitrided alloys. SURFACE TECHNOLOGY CORP. Sept.4, 1968 [Sept. 5, 1967; Aug. 27, 1968], No.41954/68. Heading C7A. A nitrided alloy with a degree of nitriding decreasing inwardly from the surface thereof consists of at least one metal from each of the Groups I, II and III where Group I = Nb, Ta and V, Group II = Ti and Ti with up to 3% (by weight) of its content replaced by Zr, Group III = Mo and W; and, subject to the following definitions: - where (a) for Nb-Mo-Ti, Nb = 20-85%, (b) for Nb-W-Ti, Nb = 10-85%, (c) for Nb-Mo-W-Ti, Nb minimum = 10E+20D and Nb maximum = 85%, (d) for Ta-Mo-Ti, Ta = 25-88%, (e) for Ta-W-Ti, Ta = 10-88%, (f) for Ta-Mo-W-Ti, Ta minimum = 10E+25D and Ta maximum = 88%, (g) for V-Mo &/or W-Ti, V = 15-90%, (h) for > 1 of Nb, Ta and V with Mo and Ti, minimum Nb-Ta-V # 20A+25B+15C, (i) for > 1 of Nb, Ta and V with W and Ti, minimum Nb-Ta-V # 10A+10B+15C, (j) for > 1 of Nb, Ta and V with Mo, W and Ti, minimum Nb-Ta-V # (A+B) (10E+25D) + 15C, (k) for > 1 of Nb, Ta and V, their maximum # 85A+88B+90C, (1) for Nb-Mo &/or W-Ti, Ti = 1-45% and Nb/Ti> 1, (m) for Ta-Mo &/or W-Ti, Ti = 1-35% and Ta/Ti > 1, (n) for V-Mo &/or W-Ti, Ti = 1-45% and V/Ti > 0À66, (o) for > 1 of Nb, Ta and V with Mo &/or W and Ti, Ti minimum = 1% Ti maximum # 45(A+C) + 35B and Nb-Ta-V/Ti # A+B+0À66C, (p) for Nb &/ or V with Mo and Ti; Mo = 2-60%, (q) for Ta-Mo-Ti, Mo = 2-50%, (r) for Nb, Ta &/or V-W-Ti, W=2-80%, (s) for Nb, Ta &/or V-Mo-W-Ti, Minimum Mo+W = 2%, Maximum Mo+W # 60D (A+C) + 50BD+80E. Broad compositional ranges for the six ternary alloys are as follows (many specific examples being given): - The following examples of higher alloys are given:- (a) Nb35, Ta35, Mo10 Ti20; (b) Nb30, Mo10, W10, Ti20; (c) Nb50, Mo12À5, W12À5, Ti25; (d) Nb37, V30, Mo8, Ti25; (e) Nb25, Ta25, V25, W5, Mo5, Ti15 (f) Ta52À4, Mo12À5, W12À5, T122À5; (g) Ta53, V22, Mo7, Ti18 (h) Ta36, Nb18, V10, Mo18, Ti18; (i) Ta42, V12, Mo26, Ti20; (j) V39, Nb29, Mo8, Ti24; (k) V34, Nb13, Ta25, Mo7, Ti21; (1) Ti40, Nb30, V20, Mo10. Nitriding may be effected in nitrogen or argonnitrogen at atmospheric pressure so that the nitrogen pick-up is at least 1mg/cm<SP>2</SP>, the surface micro-hardness is at least 1000 DPN, and the reaction depth to which such hardness is developed is at least 0À5 mil. Uses. Rotary files and burrs, taps, drills, dies, rotary seals, nozzles and tube liners.
