Abstract
Treatment is to better resistance to friction and wear and tear by the surface and involves the use of an electrolytic bath which exhibits desirable stabilisation properties. The bath, which is kept under 300 degrees C., contains additional potassium and/or sodium thiocyanate in a quantity between 0.005 and 4.00%. Iron ferricyanide which forms in situ on the surface of the object mixes with the iron sulphide.
