Abstract

Ferrous surfaces are sulphurized by immersion in molten sulphur at a temperature of at least 120 DEG C. after the ferrous surface has been pretreated to increase its meltability. The pretreatment may be any one of the following processes:- (1) Immersing in molten sulphur and applying a positive potential of at least 10 V. to the ferrous material. (2) Electrolitically polishing in an electrolyte of phosphonic acid, gelatine and oxalic acid. p (3) Chemical cleaning in an aqueous solution consisting of H2SO4, HNO3 and CuSO4. (4) Cleaning in a molten flux. (5) Treating with a sulphur containing gas such as H2S or S2Cl2. (6) Electrolysing in molten sulphur which contains lead or lead sulphide. (7) Heating the buffed surface in hydrogen at 350 DEG C. The pretreated material is then immersed in molten sulphur at 120 DEG -445 DEG C.ALSO:Surfaces of iron, steel and alloy steels, e.g. plate, are sulphurized by immersion in molten sulphur at a temperature of at least 120 DEG C. after the ferrous surface has been pretreated to increase its wettability. The pretreatment may be any one of the following processes:- (1) Immersing in molten sulphur and applying a positive potential of at least 10 V to the ferrous material. (2) Electrolytically polishing in an electrolyte of phosphoric acid, gelatine and oxalic acid at a current density of 30-200 A/dm2. (3) Chemical cleaning in an aqueous solution consisting of H2SO4, HNO3 and CuSO4. (4) Cleaning in a molten flux such as 28% NH4Cl and 72% ZnCl2 or 10% borax, 30% BaCl2, 60% CaCl2 in a mixture of two or more of borax, NaCl, BaCl2, CaCl2, KCl or AlCl3. (5) Treating with a sulphur containing gas such as H2S or S2Cl2. (6) Electrolysing in molten sulphur which contains lead or lead sulphide at a current density of 2-3 mA/cm2. (7) Heating the buffed surface in hydrogen at 350 DEG C. The pretreated material is then immersed in molten sulphur at 120-445 DEG C.
