ABSTRACT:
This invention relates to a process for electrowinning molten aluminum from alumina dissolved in molten fluoride salts which are essentially cryolite. More specifically the process relates to the treatment of aluminum reduction cell drained solid cathode surfaces to make them wetted by molten aluminum metal. This process deposits a coating composed of titanium diboride and titanium carbide on the solid cathode surfaces from supersaturated dissolved elements in electrowon aluminum. The electrowon aluminum wets the coating on the cathode. The coating makes the cathode surfaces resistant to erosion, chemical attack and penetration by the molten aluminum metal, sodium and cryolite electrolyte contained in that cell.
