ABSTRACT:
The invention relates to a process of electrowinning molten aluminum from alumina dissolved in molten fluoride salts which are essentially cryolite. More specifically the process relates to placing refractory metal raised cathode structures in aluminum reduction cells and treating the raised cathode surfaces to coat them with refractory metal borides. This process deposits coatings composed of titanium diboride and other refractory metal borides on titanium and other refractory metal cathode structures from supersaturated elements dissolved in electrowon molten aluminum. The refractory metal boride coatings are resistant to penetration by the molten aluminum metal.
