Abstract
A heat resisting and electrically conductive composite material is formed of a shaped body of a powdered boride of at least one of the metals Zr, V, Cr, and W infiltrated with a bonding metal of Co, Fe, Ni or Cr, the infiltration being effected either by applying bonding metal powder to the shaped boride body and then heating to melt the bonding metal, or by sintering the shaped boride body and then heating it in contact with molten bonding metal. The amount of bonding metal may be 3-10 per cent by volume of the boride but where lower electrical resistivity is required, e.g. for the contact of an electrical circuit breaker or resistance welding electrode, the bonding metal should be 25-35 per cent by volume of the boride. According to the Provisional Specifications the metal borides may include titanium boride and according to the First Provisional Specification the composite material may be formed from a powdered mixture of the metal boride(s) and bonding metal which is pressed and then sintered or pressed and sintered simultaneously. In the latter case the heating may be by high frequency induction or by passage of electric current.
