of coating at low temperature (30-200 ℃) is more obvious than that at high temperature (960 ℃). Key words: aluminum electrolysis; TiB2 coating; electrical resistivity; tensile strength; compressive... resistivity of TCC is reduced. In industrial aluminum electrolysis cell, the smaller the electrical resistivity of coating at low temperature, the higher the impulse voltage of coating-cell reduced during......
