METHOD OF ELECTROLYTIC DEPOSITION OF IRON-CHROMIUM ALLOY Russian patent published in 2006 - IPC C25D3/56

Abstract RU 2285065 C1

FIELD: electrolytic deposition of solid wear-resistant coats, iron-chromium coats in particular used for restoration and surface hardening of parts.

SUBSTANCE: proposed method includes deposition of coat at asymmetric AC at asymmetry coefficient of 1.2-6 from electrolyte containing the following components, kg/m³: ferrous sulfate FeSO₄, 250-300; chromium nitrate Cr(NO₃)₃, 5-20; sodium sulfate Na₂SO₄, 20-40 at electrolyte temperature of 20-40°C at interval of cathode current density of 20-40A/dm².

EFFECT: increased micro-hardness, wear resistance, current efficiency; reduced electrolyte temperature.
