Abstract

1483891 Ion implantation; hardening steel surfaces N N ENGEL 15 Nov 1974 [14 Dec 1973] 49506/74 Heading C7U A steel substrate containing 0.3 to 1.8% of interstitial alloying atoms is implanted with ions of an element which is insoluble in iron by ionbombardment, and then heat-treated to produce a superhard martensitic structure. The substrate may initially contain Be, B, C or N as interstitial alloying atoms, or these may be alloyed therewith after ion-bombardment. The steel may be cleaned before placing in a vacuum chamber as the cathode, and the chamber is flushed with inert gas prior to bombarding with ions of He, Ne, Ar, Kr, Xe, Rn, Li, Na, K, Rb, Cs, Fr, Ca, Sr, Ba, Ra, Ag, Cd, Hg, Tl, Pb, Bi, Mg, Y, La, Zr, Hf, Th, Ta, Cu, In, Se, Te or Po; preferred ions are those of size similar to Fe. The steel is then heated into the austenite range and quenched in water, oil, or air to produce a superhard martensite, e.g. of Knoop hardness above 1000, and of maximum grain size 0.001 mm.
