METHOD FOR APPLICATION OF COMPOSITE ELECTROCHEMICAL COATINGS Russian patent published in 2013 - IPC C25D15/00 C25D3/20 C25D5/50 

FIELD: electrical engineering.

SUBSTANCE: component parts are loaded into a bathtub containing an electrolyte formulated as follows, kg/m³: FeCl₂*4H₂O - 500-550, Na₂H₄C₄O₆*18H₂O - 1.5-2, Grade M14 boron carbide - 80-120, pH=0.5-1.2, at a temperature of 40-80°C. The electrolyte acidity in the process of sedimentation is corrected within the range of pH=0.7-0.9. Then one performs thermal treatment with HF currents to ensure a temperature equal to 500-600°C at a depth equal to the applied layer thickness.

EFFECT: enhanced strength and wear-resistance of component parts coatings being recovered and reinforced.
