Abstract
The invention relates to a composite material of formula: (C—N—B-MR)(Al-MR)(R)in which C—N—B-MR is one or more carbides, nitrides or borides of one or more refractory metals of group IV, V or VI of the Periodic Table and/or one or more aluminium carbides, nitrides or borides chosen from AlC, AlN, AlBand AlB; Al-MR is one or more aluminides of one or more of the above refractory metals, it being understood that: if MR=Nb, Ta, Hf, Zr, Ti or V, then Al-MR=AlMR; if MR=W or Cr, then Al-MR=AlMR; if MR=Mo, then Al-MR=AlMoor AlMo(≅AlMo), and R is a residual component other than carbon, comprising one or more phases chosen from AlC, AlN, AlB, AlBand MRtAlu(C—N—B)v in which t, u and v are numbers greater than or equal to zero, and x, y and z are the volume fractions of the respective components with x>y; x+y>0.5; x+y+z+1 and 0.01<y<0.5. The invention is also aimed at the use of this composite material as a coating in a component that can be welled by liquid aluminium and can be used in electrolysis cells.
