Abstract

The invention relates to the steel treatment processes, in particular a process for thermochemical treatment of steel articles.The process, according to the invention, includes the anode heating of the article up to a temperature of 400…950°C for 3…5 minutes, in an electrolyte containing, g/l: NH4Cl 40…60, NH2OH·HCl 0.05…0.10, N2H4·HCl 0.1…1.0, water - the rest, at a current voltage of 100…220 V and a density of 1.0…2.5 A/cm2, afterwards the article is quenched in an aqueous solution containing 50…100 g/l of sodium hydroxide.
